I was just getting on to make a ventilation post and saw you asked about it. My biggest gripe with my local B&Ms is that they don't have nearly enough ventilation. It's sufficient if there are just a couple guys in there smoking, but evenings and weekends, forget it. To be honest I avoid the local B&Ms when I want to relax and enjoy a smoke or catch a game. When it looks like Snoop Dogg's car inside and your eyes start to itch and burn, the appeal is gone. I'm far from afraid of a smoky environment but it seems like some of these places don't even try. That's probably my #1 concern when it comes to a lounge. #2 would be TVs and comfy chairs laid out in a way that it is easy to watch the TV if you so desire.
