My biggest beef with this place is that cover goes up from $5 to $10 after 12. I arrived minutes after 12 and was made to pay double what I was expecting (and I already found it odd that I had to pay anything to be allowed entrance into a dirty hipster bar). Don't get me wrong, I enjoy places like this from time to time, but not for that price!
I went on Motown night (the 1st Saturday of every month) - not exactly my thing, but it made for an upbeat vibe and people were enjoying the novelty of the tunes. I do, however, think that drinks could be cheaper given the cover charge. The crowd was a mix of unwashed-early-20's-hipster-types and seedy older dudes...so, you know, the ideal combo really.
In short, if you plan to check this place out? Arrive before 12 and keep your expectations low.
