What started as a pop-up inside is now a fast-casual hangout at Mission Rock that's perfect for pre- or post-event stopovers from nearby Oracle Park or Chase Center. Appropriately, Quik Dog's space and menu feel a lot like a concession stand, down to laminate tabletops, plastic trays, squeezy bottles of mustard and ketchup on every table, and crowd-pleasing riffs on burgers and hot dogs.
