Thomas: I have traveled around the world (in the Northern Hemisphere, at least), and I have been reviewing restaurants off and on (mostly on) for 15 years, and I have to say you are way off-base. For reasons Drew mentions, Tucson is no Portland, as we're a fraction of the size. (Also, if you think Puerto Vallarta is a good fine-dining city ... God help you. It's one of my favorite places on the planet, but it ain't because of the fine dining.)
As for your question: The food at any of these places could stand up to anything Portland offers: The Dish. Lodge on the Desert. The Cup (on a good night). JaxKitchen. The Abbey. Agustin Brasserie cound get there. And that's just off the top of my head. Other restaurants that aren't fine dining that produce amazing food: Taco Giro, Mamma Louisa's, Kingfisher (that burger!), Mother Hubbard's (if you have not tried some of their more adventurous breakfasts, you're missing out) and even El Charro (mediocre service aside, that carne seca is something).
If you want to bash Tucson food because it makes you feel good or something, have at it. But I think my credentials in terms of food knowledge and travel are strong, and I'll say this: Despite some weaknesses (especially in Asian food overall), Tucson's food scene is one of the things I am going to MISS when I move to the Palm Springs area in January.
TucsonFlickFan: When we schedule reviews, we are depending on the reliability of the schedules given to us by the promoters and studios. In this case, the film promoter insisted as late as 5 p.m. on Tuesday that the film was opening here. For some reason, it did not.
