I've been to OMB a few times now for different events, most recently the Brewer's Ball & Christmas Market. While I'm not a big beer person ( If I was I think I would be in beer heaven ) If I was. It may take you a little while to find this spot, since it's down an odd street in Charlotte.
I have to give it to this place and their marketing team for always having interesting and community/ local events. What a huge selection of beer! You can even keep refilling you own beer jugs, how clever and environmentally friendly!
I'll have to spot by during the summer months to catch some live music.
