Like any big city, Portland certainly has its share of good restaurants. And the bigger the town, the more restaurants it has, the better the selection and the competition too.
What I meant was regional cuisines that were more specific to the locales. But come to think of it, nowadays with international connectivity and the mobility of people, one can by chance find a good restaurant anywhere a good but unknown chef happens to decide to set down root. To have something really different, one may have to go to a different country.
When we were on the coastal Highway 1 recently, I saw many little restaurants or inns along the road, but did not think of looking in Yelp to check them out. Actually, we were without internet most of the time. Only when I got back home that I thought of looking up the Web, and saw some interesting places that I would not mind trying out when I was there.
