What property on the strip has the best Bloody Marys on the slot floor?
I'm guessing that most of us prefer our Bloody Marys in a glass.

Touché.

Still, I'm guessing that the best ones to lap off the floor were the best ones to have been in that glass a moment earlier. To the OP and new guy: Unfortunately I have also never had a Bloody Mary in a casino. I've probably had two Bloody Marys in my life -- although I can't remember them at the moment.
When I'm in the mood for spicy tomato juice, I usually have a V8. Okay, seriously, I did have a "virgin" of the Bloody Mary mix at the D's Vue bar when the bartender recommended it over a V8 and it was quite tasty. It was unusually spicy, however. If that appeals to you, then I'd suspect that you might like their alcohol laden version.
