Salotto 42
This cool, comfortable cocktail boîte sits on the edge of the petite cobblestoned Piazza di Pietra, facing the square’s remarkably well-preserved, marble-columned ancient Temple of Hadrian. It serves as a daytime lunch spot and evening aperitivo-hour hangout for attractive, creative locals who live and work in the historic center. Because it’s right between the Pantheon and the Spanish Steps, just off Via del Corso, it also makes for a great in-the-know find for travelers visiting the monuments. Warmer months see regulars sitting and standing outside sipping Spritzes and Negronis, while cool whether sends folks to the atmospherically lit, barrel-vaulted interior.
