Been a long time since I dragged my bones down there, but last I heard it's still the biggest meat market in the city. Has been for decades. Don't know what it is, but for whatever reason the "pickup bar" thing centers at the Roxy. Always has. The Odds used to be the house band once upon a time; back in their bar band days, they'd do their originals as The Odds (later, just: Odds) but they'd do their cover sets at the Roxy and other places as Dawn Patrol.
Carpet floors? Check. Stale beer smell? Depends when you get there. They have to steam-clean regularly. Drunk creeps? Check and a half. Undesirable girls with questionable morals? Uh...check. Also desirable girls with questionable morals.
There's a VIP bar that I, humble non-NHL player pleb, have never been invited into. Even in my bar days, even in my bar band days...never got into the VIP at the Roxy. *sigh* I know. Just didn't happen for me.
Your bro probably knows the real Roxy better than I do.
