I’m sorry I cant invite you all, but my sister has gotten us a tour bus for our friends and family to roll thru Bklyn for our birthdays in 2 weeks. I can take them all to where ever I want. Needless to say L&B pizza is a given and probably some seafood, but some proper beverage stop is definitely gonna happen...I know Torst is an easy answer. But I’d be pulling up w/ like 30 people where would you go?? We want some easy fun and not be a pblm to a any place.
The Gate in Park Slope has a really nice/big outdoor area, and a really great tap list. That would be my recommendation.
4th Avenue Pub or Pacific Standard are great places to go, and next door to each other. Also close by is Mission Dolores, but that can get packed early afternoon on a nice weekend day.
If you are looking for space, try Brooklyn Tap House (especially if their outdoor space is open) or perhaps a beer hall / beer garden. Don't bother with Torst.
Id recommend Barcade also. Probably wont find a more "fun" place than an arcade that serves 2 dozen draft craft beers.
