I need help with a phrase for a beverage tub!

My So and I are getting this beverage tub for his best friend for a housewarming gift. It's the first house hes bought. Him and his girlfriend have lived together for a year already, but they arent married. Since they arent married I dont want to put a last name on the tub. I've been trying to think of a saying/phrase to do with drinking/a bar, something along those lines. Anyone have any ideas?
