I've lived in the Portland area for a little while and here's my reviews of a couple of the clubs I've played at.
Final Table:
Has the most games of any place in Portland. Spreads 1-2,2-5,5-10 daily. Also has 1-2 big O a couple nights a week. It's in a strip mall in a slightly bad part of town but its pretty close to the airport. In addition to the shootout rules in Oregon, this place will let you chip down to a min buyin at the end of the 1 hour session in any of the games. 85% of the bad regs and fish do this in 1-2 and big O so those games don't play very deep. Dealers are a mixed bag as well as the floor. Food is pretty basic, service is below average and they only have beer and wine.
Encore: Downtown Location. You will have to park a little ways away during the daytime. Spreads 1-2. Gets pretty deep. Only 2 tables for shootouts. Shootout games start at 5pm. Younger crowd and aggressive action. Games can be great or terrible. Players are a step up from your usual 1-2 game. Floor and dealers are good. Food is good, full bar. Service is pretty slow, so just order at the bar.
Lucky Devil: It's a strip club
. Only 1 table of 1-2. The game starts at 9pm, but get there at 8pm so you can get a seat with a view of the dancers. Dancers are solid. Full bar, menu is a step up from final table but below Encore. Service is good. Good action, and the players are your normal 1-2 variety. Lighting is terrible so really check your cards well.
