Ol WacoMan... O'Shays... you really know how to slum it. Nice place to gamble, and they DO appreciate it... Although, one night we went through like 4 decks of cards, and never won a hand, in 21. We're all pretty seasoned players. The dealer got blackjack like 4 times in a row.
PiagWe loved going to the IP, until everyone felt they were too good for it. *ahem*. We asked a taxi one time, having told him to take us to the IP... "Is the IP the worst hotel?" He said, no, it was the 2nd... He said Circus Circus was a dump. Having said that... From what I understand, the IP has been purchased and should have been torn down in the last year. The only reason it hadn't, already, was because there was a drain line beneath it. That has been worked around.
Here are my thoughts...
IP if still standing usually has $5 tables during the week, and early during weekends. You can also find $10 tables during weekend nights.
Aladdin - I don't think they EVER have anything less than $25 tables.
Paris - I'll never gamble there... the pit boss was totally unappreciative. I liked their Sport Book, though.
MGM - Pretty nice.
Rio - A pain to get to. They have a pretty decent seafood buffet, so we make it over there from time to time.
Mirage - Pretty nice. We actually play poker there.
Caesars - Too stale and formal for my taste.
Luxor - pretty good, but hit or miss. The hotel is a dump.
Barbary Coast (across from Bally's) - That place is very chipper. Lots of people always having fun. Pretty relaxed. The dealers are very friendly, and give you some space to get a little roudy.

New York New York was nice. They have a little irish pub (9 irishmen?!) right there, so you can take a break.
Harrah's and Ballys are decent. Harrah's is nice, because it has the Half-Yard's, right outside.
Hooters was a joke.
I don't think we are the clientele for places like Venetian, Bellagio, etc.
I'd classify 4 types of casinos:
Upscale/Elite - Stuffy, high limits and ALL business = Caesars, Mirage, Venetian, Bellagio
Normal Places - Fun, nice, but not much riff raff = New York New York, Harrah's, Bally's, Mirage
Bottom Rung - Fun and exciting, lower limits - IP, Barbary Coast, O'Shays <- This is where we go, when we aren't feeling White collar, or have been beaten down... or just a little intoxicated.
Other - Hooters, MGM, Luxor, Rio = Places we've played, and might go again, but wouldn't go out of our way.
