We came here on a Saturday at around 9:30pm. This place is only open on Friday and Saturday from 9pm-midnight so I'm glad we were able to stop by here since we wouldn't have any other time during our trip.
This place is above The Grand on the second floor. There's a door that you can walk through that will take you to a tiny room that can probably seat like 20 people total.
All the drinks are about $12-13. I ordered the sazerac which tasted really good. My girlfriend got the blue Wallis which she did not like because it was essentially straight gin with a dash of blue curaçao.
This is a really nice speakeasy with a cool ambience. The drinks are really strong (a lot of them contain absinthe) so be prepared for that. I would definitely come back.
