Clinton Hall
Good spot for large groups in Manhattan
Domino Park - Other Half Brewing
Can get crowded but they're pretty flexible on large groups
TALEA Beer Co.
Multiple locations in Manhattan and Brooklyn but I think the Cobble Hill one has the most space, two floors and some outdoor seating in the summer.
Strong Rope Brewery
This one is in Red Hook so probably the most out of the way, but it's huge and can accommodate a lot of people. Plus the views of the water are gorgeous.
