Well, when I was in school, the "club/bar" type hangouts were mostly "on campus" (not our campus, but the Ohio State University campus 10 minutes up the street).

I often ended up at the Garage, which at the time was a gay bar with awesome dance music. Now it's a higher-scale club I think.. haven't been there in years.

By my junior year we had discovered a little bar called the Leipzig Haus just down the street from school, one of those little dive bars with locals & cheap drinks.

Now that I'm out of school, I mostly go to this great place called Mac's. It's a little Scottish pub, with the yummiest bar food & great staff.

Incidentally, I've been to a few Have A Nice Day Cafe's (Pittsburgh & Memphis) & it's a great lil' place!

This definitely isn't much after all of the big towns but here goes:

Eskimo Joe's-you've probably seen the t-shirts, it's a restaurant and after 10 it's a 21 and over bar

On the strip:
The Wormy Dog (appetizing name huh)-beer only, they have bands some nights

Murphy's-very laidback, pool and darts and an ouside area when it's not too cold (I met my husband here)

Willy's-another fun place, one pool table and there's always a band

The Tumbleweed-large country dance club, there is a smaller pop music room too-Home of the World Famous Testicle Festival (the biggest calf-fry ever)

That's pretty much it in good ole Stillwater
