LOCATED IN THE HEART OF SAN DIEGO’S GASLAMP DISTRICT , barleymash is the fun, high-energy downtown restaurant and bar that celebrates the richness of American culture through its appetizing and progressive bar fare. Both the restaurant philosophy and menu offerings draw heavily from two barroom staples: beer and bourbon. The name, in fact, refers to the typical grain mixture used in the brewing and distillation process of both beer and bourbon.
