Imagine a soda fountain and lunch counter tucked inside an art deco bar and you might have some idea what awaits you at this midtown joint. Located inside the former Stutz automobile showroom (a few sandwiches are named after models from the long-defunct carmaker), the Fountain on Locust offers soups, sandwiches and ice-cream treats for the kid inside all of us - as well as a few ice-cream martinis for the adults. Standout sandwiches include the "Prosperity Panini," with grilled zucchini and hummus; and the "Royal Grille," a grilled-cheese with slices of Fuji apple. Desserts include decadent sundaes. Ask for two spoons or surrender to your sweet tooth.
