Greater Seattle Area

[Plzr]

You didn't state what your prefered game/limit but no matter....
N. Seattle has a place called "the Hideaway", 145th & Aurora. There you'll find good action 4-8 & 10-20 HE being played in a small smoky room. If you're sensitive to smoke keep reading.
South of Seattle in Renton is "Diamond Lil's". They offer 4-8,6-12,8-16 and 12-24 HE, 6-12(w/10-20 kill)Omaha split. Good action all the time although the day crew in the big game can be a bit nitty.
The room is well ventilated and the food is rather good (1/2 price for seated players).
There are also a few indian casinos but they suck for more reasons than I care to spend time listing.
More and more of the mini-casinos have been putting in a couple poker tables and have either 3-6 or 4-8 HE or Omaha split. Look them up in the phone book and call around if you're bored and have some time to kill.
Good luck to you!
