Going to Tucson for the first time with a bunch of people and we're looking for some great recommendations for breakfast, lunch & dinner Can be ethnic, vegetarian, etc as long as the food is top notch. Will be around the Expo Center. Nothing too upscale price-wise.
Do a search here... there are several detailed recent posts and lots of posts pre-Gem show every year. For Mexican food recommendations here's a current string: http://www.chowhound.com/topics/473214
