The puffy taco. Any self-respecting San Antonian will tell you it's the signature SA dish, but the debate as to who does them best is heated. Still, Ray’s, home of the original puffy taco (which looks an awful lot like a chalupa or muchaco), is as beloved as any other SA institution. Nine times out of ten, those tacos are what you're gonna be there for, but that doesn't mean you should miss out on Ray's wide selection of other Mexican dishes, seafood, burgers and hot dogs. You can pull up into the actual drive-thru, or order inside for a beer and a trip down memory lane with its memento-lined walls.
