SoBe Burger is a British quick-service restaurant franchise serving Miami-inspired smash burgers, loaded fries, wings and sides. The name comes from South Beach. School friends Tom and Alex brought the idea back to London after a trip to Florida and launched it as a residency at London Fields Brewery in 2018.

About the network

More about SoBe Burger.

The business grew through delivery before expanding onto the high street. Sessions began working with SoBe in 2021, helping develop the menu for delivery and introducing it to local kitchen operators. That gave the brand a way to see where customers were already ordering before committing to a permanent restaurant.

The restaurant opportunity combines a branded SoBe storefront with dine-in, takeaway and delivery. Depending on the agreement, the same kitchen can also prepare other Sessions brands for delivery, including Little Bao Boy and Bangtan. That gives an operator several ways to sell from one kitchen using shared staff and equipment.

Sessions looks for compact premises in places with strong footfall. Its published brief typically calls for 700 to 1,500 square feet, an open kitchen, space for around 10 to 30 seats and access for delivery riders. Franchisees are responsible for recruiting and managing their staff, running the operation to brand standards and building relationships with local customers.

Sessions supports the operator with site selection, design, fit-out, training and launch. Its Sessions Serve platform brings together menus, orders, payments, stock and reporting. The franchise package also includes procurement, ongoing operational support, menu development and help with national and local marketing.

The published total investment range is £100,000 to £200,000. Sessions’ detailed investment page lists £60,000 minimum liquid capital, while SoBe’s own franchise page quotes around £70,000. The investment page also advertises a limited-time initial fee of £10,000 and separate charges on in-house sales, delivery sales and marketing.

SoBe is recruiting both single-site and multi-unit operators in the UK. Its store locator lists 21 customer-facing locations, while the wider delivery network reaches substantially more areas. Plymouth and Kentish Town show how the model can work in practice. Both had already demonstrated local delivery demand before a franchise partner opened a permanent restaurant.

Five Fibre assessment

How the foundations score.

Every franchise network is assessed across the five connected areas Twine Growth believes support sustainable franchise growth.

How the Five Fibre score is calculated

01 Assess Scale Ready17.5/20

SoBe has a way to test local demand before taking on the cost of a restaurant. Sessions can see how a brand trades on delivery in a postcode, and SoBe has converted some of those markets into physical stores. Plymouth and Kentish Town are named examples. That gives a prospective operator more to assess than a national sales figure or a forecast for an untested location.

  • A1, proven and profitable core model, 2.5/5. The trading estate and published sales figures support repeatability. Sessions publishes a 7% to 10% EBITDA range based on figures supplied by current operators. The public material does not identify the full cohort, period or results for the original SoBe operation, so I awarded partial credit for this criterion.
  • A2, operation without daily founder involvement, 5/5. Independent franchisees run restaurants across the UK, supported by Sessions’ operations, technology and culinary teams. Mehdi’s two-store operation is a practical example of the model being delivered locally without the original founders running the stores.
  • A3, clear ideal franchisee, 3/3. The offer identifies both first-time and experienced multi-unit operators and sets out the need for commercial judgement, leadership and the ability to manage a team. It explains which experience is preferred and what the training is designed to cover.
  • A4, realistic franchisee commercial viability, 4/4. Franchisee-supplied operating metrics, a published cost and fee structure, and a named Plymouth case showing both delivery and in-house sales support the conclusion that an operator can make money under the model. The full score reflects evidence of a viable path. Individual results will depend on the site and sales mix.
  • A5, distinctive market positioning, 3/3. The Miami-inspired menu gives the customer proposition a recognisable identity. The operator proposition is also distinct. Sessions uses local delivery demand to inform site choice, and one kitchen can serve several brands.

The commercial test is how much value that delivery history adds once a restaurant starts paying high-street rent, staffing a front counter and serving two sales channels with different charges. A breakdown of actual margins by channel and site would show how consistently the model makes that transition.

02 Build Strong15.5/20

SoBe’s operating model has to handle both a customer-facing restaurant and the flow of delivery orders through the same kitchen. Sessions has invested in a shared system for that work. It also takes an active role in site design, fit-out, training and ongoing support, so a franchisee has a defined route to getting a site ready.

  • B1, documented operational playbook, 2.5/5. Public materials evidence operating standards, training and audits. I could not verify the scope or completeness of a single SoBe-specific operations manual available to franchisees.
  • B2, structured onboarding and training, 4/4. Sessions advertises four weeks of training, support for the franchisee and team, and managed launch preparation. Mehdi’s Sheen account independently identifies training and stocking as specific steps within his onboarding.
  • B3, documented brand experience, 2/4. Menu management, food safety, site design and operations standards are visible. The public offer gives less detail on the complete service and brand standards used across both restaurants and delivery-only kitchens.
  • B4, central access to tools and systems, 3/3. Sessions Serve brings together orders, menus, payments, stock and reporting. Sessions also describes training, kiosks and food safety within its technology provision. This is a working operating system expressly referenced in its SoBe rollout.
  • B5, launch without constant founder input, 4/4. A dedicated Sessions team guides site selection, design, fit-out and training. Openings by operators including Peter and Mehdi show the support being delivered through the franchise team.

The strongest part of Build is the link between the physical kitchen and the tools used to run it. A multi-brand kitchen only adds useful capacity if the team can handle different menus and order channels during the same shift. Integrated ordering, stock and reporting address that practical constraint.

03 Launch Scale Ready20/20

Launch is SoBe’s strongest fibre. A candidate can find a dedicated franchise offer, see the property and operator requirements, review the commercial structure, and understand how Sessions takes an applicant from first contact through a site visit, fit-out and launch.

  • L1, clear franchise proposition, 5/5. The offer explains the SoBe storefront, the optional wider Sessions delivery portfolio, the compact premises model and the use of existing order data to guide location selection.
  • L2, messaging for the right prospect, 4/4. Recruitment copy explains the operator’s responsibility for leading people and running a local restaurant. It speaks to both people entering hospitality and experienced operators looking to add units.
  • L3, clear enquiry journey, 4/4. Candidates can apply online and see the stated sequence of an initial call, trade-zone discussion, store visit, site selection, fit-out, training and launch support.
  • L4, structured discovery before acceptance, 4/4. Sessions describes a fit discussion, a visit to a trading franchise and a final meeting with the Managing Director or COO. The franchise team has also run open days for prospective operators.
  • L5, plan to take the opportunity to market, 3/3. The offer is marketed through the dedicated recruitment site, open days, the British & International Franchise Exhibition, WhichFranchise and Platinum Wave. The staged programme of new openings gives that recruitment activity a practical rollout plan.

The main candidate-facing inconsistency is the £60,000 versus £70,000 liquid capital figure. The journey itself is well documented. A single current figure across the SoBe and Sessions pages would make it easier for prospects to qualify themselves before applying.

04 Grow Developing9.5/20

SoBe’s strongest expansion mechanism is the link between delivery and restaurant development. Sessions can look at where people already buy the product, then decide which markets merit a permanent store. The network has used that approach alongside new partner recruitment and expansion by existing franchisees.

  • G1, consistent monthly franchise enquiries, 2.5/5. Sessions reported more than 100 prospective franchisees booked for open days during its early rollout. The dedicated application route and live directory offer show ongoing recruitment activity. A current month-by-month enquiry series was not found.
  • G2, tracking enquiry sources and identifying the strongest prospects, 0/4. Direct applications, events, directories and an adviser are all visible. I found no public evidence showing source attribution through to qualification, agreement and opening.
  • G3, known enquiry-to-franchisee conversion rate, 0/4. No comparable UK funnel figures were published for enquiries, qualified candidates, agreements or openings. Open-day bookings and a later store count measure different stages and cannot establish conversion.
  • G4, clear territory expansion priorities, 3/3. Sessions publishes trade-zone criteria, describes how delivery demand influences site choice and has announced named openings across several UK towns. Plymouth and Kentish Town demonstrate the approach in practice.
  • G5, recruitment beyond the original founders, 4/4. The process is handled through Sessions, with a named QSR Managing Director, COO involvement, a dedicated franchise team and an external enquiry route through Platinum Wave. The original SoBe founders are separate from that recruitment structure.

The next useful distinction is between growth through existing partners taking a second site and growth through new franchisees joining. The first tests whether operators want to reinvest. The second tests whether the recruitment process can identify and prepare enough suitable people to sustain the rollout.

05 Amplify Strong16/20

SoBe’s local marketing advantage often starts before a restaurant opens. In Plymouth, the same operator moved from delivery into a storefront after building demand for the brand. Sessions subsequently published separate delivery and in-house sales figures for that site, giving a clearer picture of how the two channels can work together.

  • AM1, local customer acquisition support, 5/5. Sessions provides national marketing, local launch support, digital acquisition and delivery-platform management. UK openings have used local promotions, events and store-specific content.
  • AM2, local online presence for every franchisee, 2/4. The brand provides individual restaurant pages, addresses and links to location or ordering information. The complete operator roster was unavailable, so I could not match a current local presence to every operator.
  • AM3, ongoing local marketing plan, 2/4. The franchise materials establish ongoing central marketing and a dedicated marketing contribution, with examples of local campaigns. A standard post-launch marketing plan for every franchisee was not verified.
  • AM4, tracking performance at franchisee level, 3/3. Sessions Serve gives operators order and performance reporting, and the Plymouth case study demonstrates site-level tracking by channel. The public case does not show repeat purchase and customer acquisition costs across the whole estate.
  • AM5, generating customers beyond personal referrals or founder activity, 4/4. Delivery marketplaces, local restaurant search, walk-in trade and centrally managed campaigns create repeatable customer acquisition routes. The brand had local delivery customers in places such as Plymouth and Kentish Town before those restaurants opened.

Public reviews include complaints about delivery temperature and missing items alongside positive experiences. They are a self-selected sample. The commercially relevant point is that a delivery-first brand needs to measure the quality of the order at the customer’s door as well as the number of orders the kitchen receives.

79/100 Overall Five Fibre score

SoBe Burger scores 79/100, in the Growth Ready band. The strongest evidence is the way Sessions connects local delivery demand with restaurant development. Plymouth and Kentish Town show that a new storefront can open in a market where people already know and order the food. The franchise offer then gives operators a defined route from application to opening.

  • Launch leads at 20/20. The proposition, candidate profile, site requirements and discovery steps are publicly documented. The main issue for candidates is reconciling the liquid capital figures across the recruitment pages.
  • Assess scores 17.5/20. SoBe has a distinct customer proposition and named examples of the model being repeated. Sessions publishes operating benchmarks, with limited visibility into the spread of results across locations.
  • Amplify scores 16/20. Delivery platforms, local store pages, launch marketing and site-level reporting give franchisees several ways to attract and measure demand. The evidence is thinner on continuing local marketing plans and repeat customer behaviour across the estate.
  • Build scores 15.5/20. Managed fit-out, structured training and Sessions Serve provide operating support. Public sources explain the components more fully than they show the complete SoBe operating and brand manuals.
  • Grow scores 9.5/20. The UK expansion strategy is visible and the franchise team can recruit independently of the original founders. Current enquiry quality, channel attribution and conversion remain largely private.

The most useful test of the next phase is what happens after a delivery market becomes a high-street store. The new restaurant can add walk-in sales and improve local visibility, while also taking on rent, staffing and a second service operation. A dated UK operator roster, a recruitment funnel and representative results showing each channel’s contribution would establish how often that transition pays off and which markets are ready for the same move.
