Went to Degree 270 Saturday night with a girlfriend around 9pm. The casino was packed. They treat this like a Vegas hotspot, complete with velvet rope line leading up to a counter where you tell them where you're going and get ID'd and a bracelet. They also have a dress code (which seemed rarely enforced, considering all of the shorts, ripped jeans and flip flops we saw) and a $10 cover charge for men on some nights. So we had high expectations...
Which quickly crashed when we entered. There are a few lounge areas, but there are also odd high-top tables with linens like you'd find at a wedding. There were very few people, so the huge open areas just felt strange. The view was on 3 sides and great. Some people danced. It was too loud to be a place to lounge.
They're totally not a wine bar anymore--just a dance club. When I asked the bartender for something girly but not too high calorie, he suggested a vodka and red bull. Or vodka and pineapple. Then just shrugged. See, there actually is a difference between a mixologist and a bartender! And as others have noted, they do serve drinks in totally tacky plastic glasses. I paid $8.50 for a vodka and tonic.
It was a really mixed group, in age and dress. We wouldn't go back.
