Hello, I will be in Portland for a conference in March and plan to stay Sunday-Tuesday to enjoy the city. I am a vegetarian (not vegan) but prefer to go to regular (i.e. not specifically vegetarian) restaurants where the chefs really know how to treat vegetables and offer something other than a plate of pasta for people who don't eat meat/fish. There is not an ethnic cuisine I don't like and in addition to restaurants I want to check out the food cart scene. Thank in advance for any suggestions you might have for me.
