The new Jason’s Deli Tomball project will bring a 4,200-square-foot restaurant to Tomball Mercantile along SH 249. It joins La Viva Cantina in a retail development taking shape near Medical Complex Drive and the entrance to Tomball’s medical district.
For residents watching that stretch of Tomball Parkway, the restaurant gives a familiar name to a larger property transformation. A roughly 3.9-acre former car-lot site is becoming more than 28,000 square feet of restaurant and retail space.
And for longtime Jason’s customers, another Tomball Parkway stop means a new place on the map for muffalettas, loaded potatoes and that familiar free soft-serve dessert.
Jason’s Deli Tomball joins a former car-lot transformation
Developer Pegasus Properties 2 described deteriorated remnants of a former car lot in its request for Tomball economic-development assistance. Its proposal called for two new retail buildings near the HCA Houston Healthcare Tomball campus.
The location helps explain the restaurant focus. Medical employees, people visiting the hospital, nearby residents and drivers along SH 249 all pass through the surrounding area. New dining options here would put additional choices close to the medical district.
The project also has a local planning trail. In March 2025, Tomball’s Planning and Zoning Commission considered the final plat. City staff supported it subject to infrastructure conditions, including plans for required public improvements.
The Tomball Economic Development Corporation approved up to approximately $260,639 in infrastructure assistance, followed by City Council approval of the agreement. That support applies to the broader development. Jason’s Deli’s separate restaurant improvement project is privately funded by the tenant.
Two buildings, with La Viva Cantina in the lineup
Earlier state construction registrations outline the development’s scale. Building A, at 28220 Tomball Parkway, covers 13,200 square feet. Building B, at 28302 Tomball Parkway, accounts for another 15,225 square feet. Together, the two shell projects total approximately 28,425 square feet.
Jason’s Deli will occupy part of Building A. Its neighbors within the development will include La Viva Cantina, a Houston-area Tex-Mex concept announced for an approximately 8,000-square-foot end-cap restaurant.
A June 2, 2026, Shopping Center Business report described Tomball Mercantile as 80% preleased and named both restaurant tenants. That figure reflects the leasing announcement at that time, rather than a current occupancy count.
The development rendering also shows both restaurant names, with additional tenant space between them. It illustrates the intended restaurant-and-retail mix, although final layouts and architectural details can change.
What the Jason’s Deli Tomball project includes
The new state registration places Jason’s Deli at 28220 Tomball Parkway, Suite A-1. It describes a 4,200-square-foot tenant improvement for a quick-service restaurant, with an estimated construction cost of $800,000.
The filing, TABS2027002027, lists construction from January 4 through June 28, 2027. Those are projected construction dates, not an announced restaurant opening date.
The company already operates farther south at 22424 Tomball Parkway, which its own website identifies as Spring Cypress-Tomball. The Mercantile project adds another restaurant along the parkway; it does not introduce Jason’s Deli to an area without an existing location.
The new address is the useful distinction for diners: Tomball Mercantile, near Medical Complex Drive, rather than the existing Spring Cypress-area restaurant.
A Texas restaurant with Beaumont roots
Jason’s Deli began in Beaumont in 1976, giving this new Tomball restaurant a connection to a Texas brand now spanning five decades. Its early storefront imagery offers a different view from the modern retail rendering at Mercantile.
The concept has grown well beyond Southeast Texas, but its identity remains easy to recognize: sandwiches, soups, salads and substantial baked potatoes. The new restaurant brings that familiar mix into a development with room for several kinds of dining and shopping.
Jason’s Deli Tomball brings muffalettas—and the ice cream tradition
The Turkey Muffaletta is one recognizable example, combining turkey, provolone and olive mix on toasted bread. Reuben The Great and the Club Royale give regulars other familiar sandwich options without requiring a tour of the entire menu.
Then there is the soft-serve. Jason’s Deli’s complimentary dessert has become part of the dine-in routine—a small detail that many customers associate with the brand as readily as its sandwiches.
For Tomball, though, the larger change is the property itself. Jason’s Deli and La Viva Cantina give residents two named destinations to watch as Mercantile advances toward restaurant openings. The former car-lot tract is moving toward a new role as a dining and retail stop near the medical district.
