The drinks are great, the atmosphere is dark yet fun, but I didn't dig on the music choice. It sounded like someone made a Pandora station called "Apple Advertisements." It just didn't vibe well with every other element of this joint. But I think that's a minor complaint.
Service was fine since it was a slow night, but I suspect the speed of service might suffer a lot during a real busy night. Even on a slow night, the time it takes to make the drinks ruins the relationship building aspect of a craft cocktail/speakeasy style bar. There needs to be a balance that allows one to establish him or herself as a regular, forming relationships, while still allowing all the customers to get drinks. If the craft cocktail process takes so long that the bartender is going full speed the entire shift, those relationships are lost. Perhaps it needs more staff, or perhaps the ability to multitask drink making and chatting isn't so great here? I don't know, but that's my only reason for taking off stars. It all just felt like the drink aspect overtook too much of the bar-going experience. I'll probably go there a few more times and re-evaluate again at some point.
