Where are America's unsung food heavens?

New York, San Francisco, Chicago, New Orleans--these are the cities most people might rattle off if you asked, Where's the best food in America? But there are also plenty of cities and towns that don't receive all the attention their bigger, flashier neighbors get, but that serve as the hidden gems of the foodie world. Portland, Ore., with its community of cutting-edge chefs who have left behind pricey NYC and S.F., might be one. Bridgeport, Conn., with its surprising mix of ethnic joints might be another. I'm currently working on a column highlighting our country's unsung food cities. I'd love to hear about your favorite places that dish up delicious food but don't get enough credit.
