We stumbled across this place while my family was visiting from out of town. My mom wanted to see German Village and my dad wanted to try a proper German-style beer. After a disappointing experience across the street with crap beers, we wandered into Club Diversity and discovered my (conservative, from-Montana) parents' favorite bar in Columbus. We hit them up on a gorgeous day where the patio in the back was comfortable and inviting, found great drink prices, and ended up buying (too many, very strong) vodka gummy bears. My dad then was excited at the prospect of live piano playing and singing of snow tunes, so we went inside and befriended the very friendly customers.
I know that parents always play well at gay bars (and, since my mother looks exactly like an older version of me, it was obvious that is who they are), but the staff and patrons were friendly, the surroundings are comfortable, the prices are great, and the place is just great. If Club Diversity served food, we might have been there all night.
What a lovely little bar, and clever too how it used to be a house. It is one of the most welcoming bars I have been too. I do not feel like I am being judged in a negative context, everyone is there to socialize, hang out, and just have a good time. I have only been there a few times and each time I had a blast.
The best part of Club D is their out door patio. This is one great patio to socialize and have some great conversation. The music is not to loud but loud enough you can bob your head to it if you'd like.
All in all its a great neighborhood bar to walk too, gay or straight do not matter. I wish I lived closer to casually stop by more often.
