I sadly give North Mountain a less than enthusiastic review because I had such high expectations. Unfortunately, while the beer was fairly good, the service needed some serious attention.
We went the day after the grand opening and waited ten minutes for them to figure out where they were going to seat us when they had more than half of their tables available. Then, it took another fifteen minutes for us to get a server who would take our drink and appetizer order. By the time we finally got our beers and pretzels, we were so discouraged that we opted to go have dinner elsewhere.
Also, this place isn't nearly as kid friendly as most of the other breweries in town--it's mostly an eclectic adult menu--or if they have a kids menu, nobody told us about it.
I would definitely give them another shot, but they need to figure out how to serve their patrons in a more organized fashion.
