La Pergola
Vegan: on request, off a standing six-course vegetarian menu
La Pergola is the obvious place to start, because it is the only three-Michelin-star restaurant in Rome and one of the few that prints a dedicated vegetarian tasting. Heinz Beck, who has run the kitchen atop the Rome Cavalieri since 1994, has long built lighter, produce-driven cooking, and the kitchen will adapt that six-course vegetarian menu to fully vegan, along with coeliac, diabetic and low-calorie diets, when you ask in advance. Flag vegan when you book and confirm a day or two before.
