Went here with a friend while I was 20. Had clear Xs on my hands, drinking water. My friend came back with 2 beers for himself. Staff comes over and asks for my ID. I handed it over, clearly not concerned because I wasn't doing anything wrong. They proceeded to ask me to leave. I asked why and they stated that i was using my friend to buy me drinks. At no point in time did I even look at his beers or put my water cup down. They kicked me out and let my friend stay... even though they believed he was the one who was performing the illegal act. SCREW this place. Needless to say, I haven't been back since I turned 21.
