re: Atlantic City
My personal experience:
Borgata - biggest and nicest. Lots of soft players that deposit $100 bills like they're at slot machines, but also some good players to be aware of. I've only played 1-2NL there and I've read that 2-5NL is very similar but with a higher percentage of good players (maybe some fledgling/lower limit pros??). I've only played there once, but due to the action and quality of the room I think it'll be the #1 choice during prime hours (weekend nights 11pm-4am). Plus-as the guy above noted-the waitresses are on the attractive side of the spectrum.
Tropicana - decent size room, several 1-2NL games going at all times (even at low tide ~5am there are 3+ 1-2NL games on weekends). The play can vary a lot so don't be afraid to change tables if you run into a tight table or a big stacked table captain not willing to call when you have a good hand. I've logged about 32 hrs here, and have a decent record there so I usually "head to the Trop" for a warmup session when in town. Plus that qualifies you for the $129-ish poker room rate, which is pretty solid for beachblock casino lodging.
Bally's - Decent sized room, though it doesn't seem to have as many players as the Trop. Lots of weak players there, along with some regulars. Of all the AC casinos I've been to, Bally's seems to have the lowest percentage of breakeven/winning players. I've seen a fair amount of sloppy play from obnoxious older guys that can get annoying (even though its profitable). Overall it's worth a shot due to the weak players, imo.
Ceaser's - Only one session there and it was a late one (5am-10am). There were about three tables going: 1-2NL, 2-5NL, & stud or Omaha forget which. Unfortunately for my bankroll, I played a session there after celebrating a winning session at the Trop and closing down a gentlemen's club (after closing down Hooters @ 2am). Needless to say I found the one rounder there-a college age kid-who proceeded to call every time I bluffed him.. Not good . Anyhow, the room was reasonably nice and the staff was attentive. If the room fills up on weekends it's probably a good game.
That's all I got so far. Going again this weekend to put in some hours. Planning to go Trop-Borgata-Harrah's.
