Bw3 is a chain so I'm not going to comment on the food. It's wings. But a few comments:
Positives: a non-smoking bar! In Las Vegas! Also, generally able to accommodate game requests since there are so many TVs.
Negative: the servers are typically on their game, but if you sit at the bar there's a 50-50 chance you'll be served (or even greeted for that matter) in a timely manner.
I wouldn't say "go somewhere else"...it's a good sports bar. Just don't have high expectations.
