Ever since its opening in 1938, Pierluigi has been a favorite with foreign residents of Rome and Italians in the entertainment field. On busy evenings tables are almost impossible to get, so make sure you reserve well in advance. Seafood dominates (if you're in the mood to splurge, try the lobster), but traditional Roman dishes are offered, too, including fried zucchini blossoms and simple spaghetti. Though the dining room, complete with stone arches, is perfectly pleasant, seats outside on the piazza are unbeatable in nice weather.
