What to Know
The Sunset Walk co-branded restaurant in brief
A first for the Orlando area: two national brands sharing one address, one kitchen, and one combined menu.
Two brands, one roof. Savvy Sliders and Fat Boy’s Pizza will share a single 2,500-square-foot storefront and a combined menu of oversized pizza and premium sliders.
A familiar corner. It takes over the former BurgerFi and Anthony’s Coal Fired Pizza space at the Promenade at Sunset Walk, steps from Margaritaville Resort Orlando.
Opening soon, hiring local. Doors are planned to open within about 60 days, with roughly 20 new jobs for the Kissimmee area.
Sunset Walk is about to gain a dining concept the Orlando area has not seen before. Savvy Sliders and Fat Boy’s Pizza, two fast-casual brands owned by Michigan-based Happy Group LLC, are combining into a single co-branded restaurant at 3298 Margaritaville Blvd in Kissimmee. Both brands sit under the same parent company that operates BurgerFi and Happy’s Pizza, and this location marks the Florida debut of Louisiana-born Fat Boy’s Pizza.
The 2,500-square-foot space is a familiar one. It previously held a co-branded BurgerFi and Anthony’s Coal Fired Pizza and Wings that opened at this same Sunset Walk address in 2023, a short walk from Margaritaville Resort Orlando. A second Florida location is planned for Fort Lauderdale, with more expected across the state.
What’s on the combined menu
Fat Boy’s Pizza built its name on enormous, plate-dwarfing slices and whole pies as large as 30 inches across, rounded out with wings, salads, fries, house dipping sauces, milkshakes, and a chocolate chip cookie cake. Savvy Sliders brings a fresh, elevated approach to the slider, built on options like Angus beef, cod, breaded chicken, or a meatless falafel, with chicken tenders and thick frozen-custard shakes on the side.
At the co-branded locations, the two menus merge, so a single visit can cover a slice, a slider, and a shake without a second stop. For a market that runs on families, tourists and mixed groups, that range is the whole point.
Taking over the former BurgerFi space
The address at 3298 Margaritaville Blvd sits inside the Promenade at Sunset Walk, the retail and entertainment district next to Margaritaville Resort Orlando. The prior co-branded tenant, a BurgerFi and Anthony’s Coal Fired Pizza and Wings, opened here in 2023, so the new concept steps into a proven restaurant footprint in a high-traffic tourist corridor rather than starting from raw space.
The location is set to open within about 60 days and plans to hire roughly 20 employees, giving the local labor market a modest lift heading into a busy stretch for the area.
Why pair two brands in one space
Co-branding is not a new idea. Diners have seen it for years in pairings like IHOP and Applebee’s, or the Taco Bell, KFC and Pizza Hut combinations. The appeal is straightforward: one location can reach a wider set of cravings, share overhead, and simplify operations behind a single counter.
Industry research points to dual-branded stores pulling in around 50 percent more sales than a single-brand site would on its own. That math is part of why the format is seeing renewed interest, from Yum Brands broadening its multi-brand mix to national chains testing paired concepts. In a tourist-heavy market like Kissimmee, a two-in-one menu also quietly answers the group-dining question of where a mixed party can agree to eat.
Kissimmee’s retail momentum
The co-branded restaurant joins a stretch of new retail activity across Osceola County. Trader Joe’s is bringing a 12,500-square-foot store to 2003 W. Osceola Parkway, a buildout valued near $958,000. Mecatos Bakery and Café is opening its first Osceola County location along Vine Street, an investment topping $2 million including the property. A separate corner development at U.S. Highway 192 and Partin Settlement Road is planned with two quick-service drive-thru pads and a multi-tenant building.
Underlying all of it is population. Osceola County has expanded by about 70 percent over the past two decades, is now home to more than 460,000 residents, and is projected to pass 700,000 by 2050. Restaurant and grocery operators tend to follow rooftops, and the county keeps adding them.
The Sunset Walk opening by the numbers
The figures show a small restaurant landing inside a fast-growing county, in a district built for steady tourist and local traffic.
A light real estate read on the opening
For the Kissimmee and Four Corners area, a quick turnaround of a vacant restaurant pad is a healthy sign. Turnkey spaces that refill fast, especially in a resort-adjacent district, tend to point to steady foot traffic and confident operators rather than a corridor cooling off.
For homeowners near 34747 and the wider Osceola County market, national brands choosing this stretch adds to the everyday convenience buyers weigh: more dining, more retail, and shorter drives for the essentials. It is the kind of incremental amenity growth that quietly supports a neighborhood’s appeal over time.
The Takeaway
The Savvy Sliders and Fat Boy’s Pizza co-branded restaurant is a small opening with a clear read on the market. It refills a proven pad at Sunset Walk, brings a first-of-its-kind pairing to the Orlando area, and adds about 20 local jobs within roughly two months.
Watch the opening date and how the combined menu performs in a tourist-heavy district. If it lands, expect Happy Group to keep pairing brands across Florida, and expect Kissimmee’s retail corridor to keep filling in.
