I think there are 6 seats in there all at the "bar." The sandwiches are pretty damn good, though and you can get small samples of all their beers for like $0.50 up to a buck depending on the beer. I took my son with me an it was a bit awkward because it was crowded and it seemed like people thought it was a bit odd to take a kid in there. In nicer weather they have seating out front.
You can also buy their beer cold in the other room along with t-shirts and glasses and stuff.
