Trillium’s Fort Point flagship on Thomson Place stacks a taproom and full restaurant, a street-level patio, and — in the warmer months — a roof deck up top with open sky and Seaport views. When the deck is running, it’s one of the better spots in the neighborhood to drink the brewery’s cult-favorite IPAs outdoors, with cocktails on hand for anyone in the group who’s beered out.

Walk-ins are always welcome, and smaller parties can reserve ahead through Resy rather than gamble on a sunny Saturday. The rest of the building carries the load when the weather doesn’t cooperate: a proper kitchen downstairs, a draft list that shifts constantly, and an evening cocktail lounge tucked inside. Best treated as a leisurely afternoon session; expect a wait on warm weekends, and bring the dog only as far as the patio.
