I really like the 1/3 at Bellagio and 1/2 at Caesar’s. Both of the poker rooms are super nice and the players are generally nice as well. As Mike McDermott would say, “the nicer the guy, the poorer the card player.”
I’ve also played at PH…definitely a lot of action, especially late at night. The poker “room” (more of a section, really) is basically in the middle of the casino, so it’s pretty loud…not necessarily a bad thing, but something to keep in mind.
