Went last night with a group of friends. I want to point out a few things that we noticed.
It cost $10 to enter The Evening Muse.
They have a single bathroom to share between the crowded room.
They don't serve liquor or anything else besides beer and wine.
The music is blaring loud, so speaking with friends must wait till the band takes a break.
Based on the other 5 bars on the same street, and many more bars in the area, I don't think I would recommend this place. If I want to go to a concert, I'd rather go to Fillmore in the music factory. If they removed/lowered the entrance fee, and added more drink options, then it could be worth it.
Overall it could have been a nice late night place, but they need to work on a few things first. Since there is a lot of competition in Charlotte.
