Ya. The UK is weird if they are using continuous shuffle for their standard BJ games (which it sounds like they are). No idea who would play that (unless you're playing online of course).
As for Harrah's STL, they definitely have a BJ crowd, but the last time I was down there I managed to find a seat and made a decent killing. I played Pai Gow on that trip too and you guys have a slightly different variation than the one I was used to playing around here and everyone looked at me like I was an idiot for asking about the slightly different rules.
I think the best way to describe Harrah's St. Louis is that they have unbelievably amazing staff, but for the most part, most of their patrons are complete dicks!
