The only place I have played was Northern Quest, and I only played there once. It had about 10 tables if I recall. Can't tell you much more about the play there
Poker is sort of on a decline in Western Washington - some casinos have abandoned their poker rooms and some have just reduced in size. I will make an assumption that the same is probably happening in Eastern Washington, but this is just a guess.
Good luck.
