I had a very nice dinner at the Heathman but it’s been years ago. Just checked the menu and it sounds like similar cuisine - local products with a French twist. Nothing earthshattering, but nice for just passing through. https://www.heathmanhotel.com/dine/the-tavern-at-heathman/
For lunch I’d suggest the Sellwood neighborhood, they have really nice, creative cafes and small shops to browse if you have time. There’s also the food trucks downtown along 4th Ave.
I’d suggest a side trip to Newport instead of Depoe Bay if you get to do the Coast for a food jaunt. There’s a restaurant on the water there called Clearwater. Ziggy enjoyed it when he was visiting: Oregon/Cal Coast - #39 by Ziggy (scroll down)
