Felt very authentic, very cool find. Loved the fact it is tucked away and hard to find. You press a buzzer and the doorman looks through his peep hole, then says he will come back once he sees if there is room then lets you in. We only had to wait in the back bar area for about 5-10 mins before we got a table. Very dark and ominous feeling down there, but the furniture, walls, etc really takes you back. Fantastic drinks but very expensive, although I expected that. We only stayed for one drink for the experience. The ambiance was unique but so non-energetic that we would have fallen asleep eventually, needed to keep our night going so we moved on. I give four stars because it was very good, but also not five as I was not blown away either.
