The food is alright (actually the brussel sprouts are bomb) and I love the live bands. My biggest issue is the service. I've been to copper blues probably 5 times and each time the service is well below average. Once or twice I'll say "okay maybe they're understaffed", but it's every time.
For example forgetting drinks and now checking on tables. It's taken 20 minutes to get a drink twice and last time they for got an order of food and drinks. If the service were good I say solid 4, maybe 4 1/2 stars.
