5 "See And Be Seen" restaurants in Boston.
Terra is the restaurant on the top floor of Eataly in Back Bay with a great outdoor patio and some very nice plants.
As you probably guessed, the Rooftop at Revere is the Revere Hotel's rooftop bar. It's got couches, an indoor pool, and decent drinks and bites.
Alden & Harlow in Harvard Square serves good, not great American small plates in a fun underground space with excellent cocktails.
