Beer pong.. Yes I know you can play it on the strip at O'Sheas or something, but playing it here just seems more *sanitary* if that makes sense. The tables are always empty, and the bartenders are pretty friendly and will give you new cups, and even cups filled with seltzer water to clean your ping pong balls with.
Budlight $11 a pitcher, or you can upgrade to Stella for $15 a pitcher (yup we got crap for playing beer pong with Stella.. whatever we wanted to!)
So the clientele at GVR is a bit well... old. We definitely get stares when we play beer pong, but that's half the fun.
