If you live in Vegas and watch Bar Rescue you may have caught Bar 702 (formerly the Sand Dollar). I'd say not much has changed in terms of the amount of business. We stopped in on a Saturday night and were unfortunately met with a cover charge. There were two live bands set to play that night and based on the noise level and lyrics I'd say they were designed for a very specific crowd.
The first band, Jesus Christ and Free Beer (I believe), was super loud and very vulgar. Personally, we thought they were hilarious based on the fact that they apparently did not care a whole lot if you liked them or not or if you were offended by what they were saying. Although, their lyrics were extremely explicit (they could be the house band at Absinthe) we found them funny, but they are certainly not for everyone...or probably most people for that matter.
We didn't stick around for the second band because by then we got a sense of the bar and were ready to move on. For a Saturday night the prices were solid but I think the employees + band members out numbered the patrons. The bars location is really working against it since there aren't a whole lot of other restaurants and bars in the area so the chances of hopping to another spot isn't likely.
