On the patio at 54 Mint, suspend all disbelief and imagine yourself on a Roman piazza, shaded by historic architecture and ginkgo trees—that is, if you can get past the sketchy surrounds on Fifth and Mission streets. Named for the Old Mint building, Mint Plaza is an outdoor expanse showcasing fresh flowers, artisanal coffee and, of course, homemade pastas to savor with a glass of vino. This casual trattoria serves rustic fare made from primo ingredients: organic potato gnocchi are tossed in a hearty and aromatic beef ragù; while a char-grilled skirt steak is served with sauteed broccoli rabe and a drizzle of olive oil. Those impressed with the ingredients may take some home; the space is stocked with mouthwatering Italian groceries for purchase.
