Family atmosphere and a classic Roman elegance permeate the spacious, well-lit rooms of this venerable address, Rome’s oldest restaurant (feeding guests since 1518!). The atmosphere is convivial yet refined, with a lovely mixture of regulars and locals. The broad selection of antipasti is displayed on a long table at the entrance, and the daily menu features authentic cucina romana that is heavy on offal—if you’re not a fan, be sure to bring your Italian/English dictionary. You’ll also find classics like cacio e pepe, plus myriad vegetarian choices. The wine list includes interesting local labels, and the staff and service are impeccable.
