I haven't been there in even longer, but there's a french cafe called I think, "La Patisserie" with great pastries and occasionally interesting ice cream.
I had a chocolate blue cheese ice cream from there that was absolutely stunning.
There is a really wonderful Izakaya in Hillsboro, in the basement of the old Hillsboro library. The sushi is fresh, the soba noodles are firm and tasty, and they have a good sake selection, if I remember right.
And Salt & Straw icecream (on Albany, I think.)
If you want a nice hangout, I LOVE Townshend's Tea Cafe. Large selection of actual tea varietals in addition to all the vanilla orange blossom lavender chai kombucha.
Good Neighbor Pizza near the airport is a really nice spot, and they do an interesting version of a personal sized stuffed pizza.
There's Pok Pok, of course, but if you're in L.A it's less exciting than much of the local fair. If you're not able to take advantage of LA's extensive Thai Town, it's worth checking out.
