Hamburger: Tilt Burger in the Pearl District. I'd give it an 9/10

Anything on 23rd Ave is good. Theres a Mexican Place called Pepinos that's good and another place Little Big Burger right next door. The best part is you finish dinner and then walk down the street for some ice cream at Salt and Straw.

Also you have to stop at Voodoo Donuts at some point for the experience.. get a picture by the "Keep Portland Weird"

They also have some really good food trucks on Division street or by Pioneer Courthouse Square.

If you are going with kids go to OMSI, its a blast! Even if you're not going with kids you can have fun at OMSI and do a submarine tour which is really interesting.

Have fun! I'm jealous!
