Ai Tre Scalini is a bar in Rome that serves local dishes and snacks, a 10-minute walk from the Colosseum. The menu includes lasagna, ravioli, meatballs, tiramisu, and caprese salad, and the lasagna uses thin noodles and ragu sauce. Within 30 minutes of opening the bar was already crowded, and the indoor seats with air conditioning required waiting while staff explained the menu. The food is good, but the portions per plate are on the small side.
