During its five decades of family ownership, Armando al Pantheon has been dedicated to serving straightforward classics to both loyal regulars and visiting tourists. You come here for simple and excellent Roman food, like ajo, ojo, e peperoncino (spaghetti with garlic, oil, and chili), trippa alla romana (tripe simmered with tomato, mint, and pecorino), and coda alla vaccinara (oxtail stew). In old school fashion, Armando al Pantheon is closed Saturday nights and Sundays. It’s also one of the toughest reservations to get last minute, so be sure to book well in advance.
