Best characters now are at The Las Vegas Club. My haunt from time to time, when I stick around down there.
But all the books have their regulars, in the dyas it is the horse players, and in the afternoon the baseball junkies. During football there are all kinds.
It is about the best for watching games, although none are all that great downtown, definately not the Strip as far as comfort goes. But you get better numbers so that is all that matters.
