Here's a link I've found helpful as I researched Portland. I searched for restaurants around my hotel and the arena here- you can sort them based on distance and by type of food, service (like late night dining).
You can also compare locations/maps with the tri-met maps (Portland's transport system): portland transport (trimet)
Let's have a late night Goldenskate dinner at the Roxy one night! Or meet there for breakfast.
Any Portlanders with suggestions?
I'm also going to try out Equinox and Echo if I can find the time, as well as some other places... I started a list somewhere... ach, I'm starting to stress...
