I went here last weekend for a sister-in-law birthday. Fun atmosphere. Great place to grab a drink, and maybe even watch the baseball game on a Sunday.The crowd is eclectic and mixed ages, and I would say a little more toward the "trendy" side but not like Scottsdale crowds, and definitely not many hipsters like you normally find in Downtown venues. Casual and cool.
They had a live band playing some good tunes, and when they were on break the music on the speakers was a lot of alternative music which I love and never hear at bars.
I really enjoyed the atmosphere at Copper Blues. I would definitely come here again to have some beer and cocktails..
