Ok. I've got this. My wife and I live in Portland and are total foodies.
Breakfast: Besaw’s (Slabtown). Also check out their bar, the Solo Club after dinner.
Lunch:
Kenny & Zukes Deli
Porque No
Dinner: So many options... here are some of our recent favorites
Q (try the osso bucco).

Trifecta Tavern (try the pork shank, crab pasta, or the burger--best one in Portland). Great place for cocktails and dessert

Urban Farmer
Imperial
Ox (steaks to die for, but there will be a long wait)
Or if you want to try some cheap hipster food:
Luc Lac (huge line around the block for happy hour food)
Bollywood Theater (not actually a theater)
Dessert:
Imperial
Rimsky Korsakoffee (occult/haunted house themed dessert place. You must see the bathroom upstairs on the left. There is a surprise in there that once made one member of our group pee her pants.)
https://en.wikipedia.org/wiki/Rimsky-Korsakoffee_House Unfortunately there is a homeless encampment nearby, so watch your 6 and consider using Lyft to get there and back.
Salt & Straw Ice Cream (long lines)
Ruby Jewel Ice Cream
Bars:
Tope (rooftop bar in a new fancy hotel, but in a bad neighborhood. Worth it though).

My comments on what's been suggested so far in this thread:
Boke Bowl: Yes! Great spot for lunch.
Bamboo Sushi: Good choice, but you pay a premium for "sustainable" sushi, and their menu is limited.
Yama Sushi is better, although still spendy.
Voodoo Doughnuts: way overrated. Mediocre doughnuts with some funky stuff on top. If you want to be involved in a shooting or stabbing, head over to the vicinity of Voodoo Doughnuts around 11pm to 2am on Fri or Sat night. But, if you want good doughnuts, go to Blue Star.
Deschutes is a solid choice for really good pub food. You can do better, IMO. Check out Cascade for some sour beer, or
West Coast Grocery (not actually a grocery), or
Breakside in the very hip and clean Slabtown neighborhood.
Salty's on Marine Drive? Pass, unless you want Red Lobster type food and need to pick up some meth in Delta Park or Camas.
