It should be quite a Community Board meeting tonight.

On one side of the ring: A small group of Union Street neighbors, who claim the club noise is unbearable; that it’s ruining their lives.

On the other side of the ring: Union Hall, the popular library-style bar/restaurant/music club on Union Street near Fifth Avenue.

The neighbors want to take away Union Hall’s liquor license.

Union Hall is trying to pull together a big crowd of support. They’ve even got a logo: Union Hall is Park Slope: I Support Union Hall.

The meeting is at 6:30 tonight at Brooklyn Borough Hall.
