Casino only here, I haven't stayed in the hotel rooms.
I think the interior decor is eh, the dealers were also eh, none too nice, a lot just a bit unattentive (inattentive? nonattentive? you get my point)...
Anyway, I love the location of Monte Carlo, I loved the Beatles Cirque du Soleil and I think their shops are pretty darn nifty, so they're "A-OK" in my book.
