Good luck finding the entrance.
I always take first timers here and get a good laugh if they can't find the entrance. It's not that hard. It's to your left.
Enough about the hidden door. This place is more about the drinks. They change their menu seasonally. But it's always a nice touch and makes me want to come back even more. Drinks are about $10-15. But who cares about the drinks? Get a punch bowl. $45-55. Enough for 4 people, or 2.
The ambiance is super trendy. Never been here just wearing a t-shirt. I would feel left out. Weekends are always busy, so expect your drinks to take a while. There's always a DJ spinnin' some tracks.
Bottom line: good place for hang outs, drinks, maybe music. And when you're peeing, expect to watch people.
