I miss Planet Hollywood the most. I think I lost one session out of dozens there. The tables had loud, fun, wild conversations. Almost everyone was drunk. People were happy to call you with marginal hands on the river because they're in vacation mode. The front desk knew me by name. Lots of nostalgia for that mini "room" in the middle of the loud casino floor.
I remember on one of my very first time's in Vegas that I walked past the Mirage poker room. I was too intimidated at that point to play live poker though (probably 21/22 years old back then). Then I saw Rounders and all I could think about was Vegas and the ... Mirage.
