Mirage.
Every morning my buddies & I would play 3/6 from 8am-ish until lunch. The dealers were personable,friendly & remembered us even though we were only there ~12 days a year. Played with a lot of the same locals (mostly retirees) every trip & got to know them a little bit. Game was easy way to start the day & they had good promotions (AA cracked especially). Matt, the overnight poker room mgr, was a good kid. The comp rate was pretty good & I always spent it at the Carnegie deli. Also, the restroom on the other side of the main cage is one the the biggest/cleanest on the strip. If you know of a "nicer" one, let me know. I want to check it out.
I miss Mirage Poker Room every time I go back.
