I'll be visiting Portland next week with my girlfriend and would like to take her out for her birthday. After doing some research on the boards, I've narrowed the list down to the restaurants listed below. We will be spending two nights in Portland, one of which will be the birthday dinner. Price is not an issue. We would like a quieter atmosphere. Also, ideally I'd choose a restaurant with sufficient portions that deserves the price tag. Location is not a big issue, but it would be nice to go somewhere located in a nice area to walk around afterwards.
