Located on a secluded stretch of beachside road in Longboat Key, Fla. — a 12-mile-long barrier island between Sarasota Bay and the Gulf of Mexico — the newly opened Whitney’s is the first casual restaurant contributing to the stable of Modernist architecture for which the area is becoming especially known. Reimagined by the Brooklyn-based firm Studio Tack, the former 1950s service station houses an order-at-the-counter diner and an open-air bodega overseen by the chef and Wolfgang Puck alum David Benstock.

The building’s original drive-in canopy and oversize garage-style windows are now accented with booths and banquettes with shrub-patterned upholstery, a tropical mural by the mixed-media artist Ty Williams and outdoor vegetation like lush bougainvillea and towering gumbo limbo trees. On the menu are seafood dishes — from grilled fish tacos with cabbage slaw to blackened fish sandwiches topped in aioli, pickled onion and tartar sauce — and Gulf Coast-inspired snacks. The bodega is stocked with to-go provisions as well as beach-going items like umbrellas and fold-up chairs.
