There is little I can say about Book & Stage that Misti Y. hasn't already said. I can't compete with her eloquence, so I'll keep this one short. B&S is a pretty cool place to see music that you probably wouldn't be able to see anywhere else in town. It's a lounge in the old-Vegas style - and I'm not talking about the decor. Sound is good enough, viewing area and seating seem to be fine. So why 4 stars? Because where else in town would someone like Black Joe Lewis play 4 nights - and with $0 cover? So why not 5? No smoking. For a Vegas lounge, that's sacrilege.
PRO-TIP. You can smoke 6 inches outside the demarcated venue space, and still have an acceptable vantage point.
