Alvarium is a really nice, cozy room, with a big bar and table area. The room is very spacious. When I was there, it was also very full, so that's a good sign, but a touch cramped, if that was at all possible, given the size of the room. Still, a very pleasant experience, with really good beer. Small criticism: there are too many IPAs on the menu. Pet peeve: the "Order Here" sign is higher than eye level, which caused no small amount of tsuris for the Bartendress, who got a little annoyed with me because I was not at the proper place in line, despite being the next to be served. So sign could be lower, and I'll admit maybe I should stretch my neck too. No biggie. Just an observation.
