I visited the Blue Martini on a Saturday night, We arrived about 7ish and found a table with a wonderful view of the band. I must say, this is the place is always my first choice when I am in Phoenix. The servers are very friendly, attentive, and provide perfect drink recommendations. The security staff keeps a close eye on the crowd and ensures everyone safety without compromising a great time. The martinis are cold, strong, eye catching and worth every penny. (for those who say they are too pricey I believe buffalo wild wings has cheap martinis, you may want to try that place). The food is also highly recommended, I have sampled just about everything they offer and I don't think I have ever ordered anything that I did not enjoy.
If you are in the area you should stop by, happy hour pricing is great and if you like them on Facebook/Twitter you will see when they post specials and super fun events.
Bottoms up my Phoenix loves!
