Pizza Schmizza. About 325 locations.
There are a couple restaurants in John's Landing (just south of downtown). A hawaiian place and a burger joint. Can't recall the names. They're literally around the corner from each other. I'll have to ask my friend who still lives in the neighborhood. There's a mexican place in the Pearl. I think it's within half a block of the DWR showroom.
edit: Bamboo Grove
Hawaiian Food Portland restaurant
If you can, go out and have a nice dinner in PDX, too. There are a lot of great restaurants, particularly in the downtown/Pearl/NorthWest 23rd neighborhoods. Free bus/trolley system within the downtown area, too, IIRC.
