It's basically what one would expect from a poker room in the Hollywood Casino franchise. Cordoned-off area in a corner of the casino, home to 10-12 (??) tables.
I usually play in the early evening and there's always a full or near-full 1-2 game going; I don't play the tourneys but they seem to have good participation.
Play isn't spectacular but not terrible. Usually there's one habitual raiser at the table and if you stay out of his way--unless you're holding the nuts--you'll do OK.
