In the heart of the city's student-filled San Lorenzo district, Da Franco ar Vicoletto is one of Rome's few affordable fish restaurants. The prix-fixe menu is always more or less the same: an appetizer of sautéed mussels or clams; a choice of seafood lasagna, spaghetti with clams, or pasta with beans and shellfish (a seemingly strange combination that succeeds heroically); and then grilled, roasted, and fried fish. It's the kind of place best visited in a group -- the more people at your table, the more food that pours out of the kitchen.
