If you're new to Tucson, or coming back for the gem show, there's a lot of new restos happening: Anello for pizza; Seis Kitchen has a brick and mortar now; Boca Taco has moved; Culinary Dropout has opened; Sushi Lounge has dim sum, etc.). Tucson Foodie has links on their website to three Taco tours worth checking out (see link).
El Guero Canelo got tagged by the James Beard Foundation for their Sonoran hot dog (which my husband and daughter love but I find ghastly).
Anyone interested in starting a "Best of Tucson" thread? (Just thought I'd get some activity going here, if possible.)
