"Armando al Pantheon has been serving straightforward classics throughout its six decades of family ownership. Come here for simple and excellent Roman food, including fantastic amatriciana made with rigatoni and a sublime spaghetti alla carbonara. You can get a half-portion of pasta if you want to save some room for a second course, like the saltimbocca alla romana or the tripe cooked in tomato with pecorino cheese. Just make sure to book your visit in advance—Armando al Pantheon is closed on Sundays and remains one of the toughest reservations to get last minute." - gillian mcguire, annie replogle
