"Right across the street from Balboa Park is Roxie Food Center, a tiny convenience store with near-constant lines of people seeking tuna melts. We always ask for ours on dutch crunch with a light toast—that way the bread gets even crispier without getting so toasted that it loses its chew or dries out the fish. For a non-canned fish option, the Simon Special with turkey and pastrami is great, too. Either way, pack a blanket to lay on the grass with your sandwich at Balboa or walk about a block down to find a bench." - julia chen 1, lani conway, patrick wong
