This ultra-traditional trattoria, complete with paper tablecloths, a TV showing the game, the owner chatting up the ladies, and a bustling crowd of patrons waiting to be seated, is a Trastevere neighborhood stalwart. Start with cheapo plates of fried tidbits, from rice suppli to cod to vegetables, then move on to the namesake pasta cacio e pepe or other classic Roman pasta dishes—and be ready for hearty portions. For secondo—if you have room left—consider polpette (stewed meatballs), saltimbocca alla romana (veal cutlets with sage and ham), or grilled meats, all sold reasonably priced. They even have pizza for the kids.
