Make sure you stop in on Saturday and ask for Patrick. They should charge for admission, as every time he serves a drink he also serves up a bit of conversation like you'd hear in any of the best comedy clubs in the country. The guy is hilarious and will pour a mixed drink to make you sure to remember, or rather not remember. Not to mention, the other bartenders which I would liken to a cream of the crop of some of the best chicks in Madison. Mondays is the best, you are only cheating yourself if you pass it by... make sure you get there if not for the fantastic drinks, then for the free stand-up routine.
Pros: Hilarious Bartenders, Insanely Strong Drinks, Good place to check out some of the UW Eye Candy
Cons: Its a smaller bar, so you want to get there by 9 to avoid a line
