There is a kids type of place called KK, and there is another right down town called liquid 8. Then if you feel like a little drive, there is one in Appleton called Sharks place.
It has been a few years since I have been there, but if you are going on a Sunday, the go to THE BAR, they have tables (only bar boxes), great food and cold beer. Oh yeah, I almost forgot, they also have lots of horny drunk women...
