I graduated from Miami in 2005, so assuming that the restaurants haven't changed, here are the noteworthy spots:
 - La Bodega:  Good sandwich shop with a "hippie" flair....think hummus, sprout salads, etc.
 - Kona Bistro: Another nice place with a creative menu with a gourmet aesthetic
 - Fiesta Charra:  Cheap plated Mexican
 - High Street Grill:  One of the nicer places in town that people tend to bring parents, grandparents, etc. (in uptown)
 - Steinkeller:  authentic German style food with a good European beer selection, known for their fried pickle spears
 - ??:  Italian place across from the CAB building.  Decent food, nicer setting
 - ??:  The restaurant in the Elms Hotel off of Main street is decent Italian in a pretty nice setting
 - Skippers:  good greasy bar food, great fries, gyros, etc.
 - Bagel & Deli:  steamed bagel sandwiches.  Ever been to Chicago Bagel Authority in Chicago?  It's a replica of Bagel & Deli....but the Oxford original is so much better if not overpriced
 - Johnny's Deli:  kind of far from things, but decent take-out sandwiches and pizza...epitome of late night drunk food
 - Burrito Loco:  similar to Fiesta Charra but not downtown
 - Patterson Cafe (I think)....it's next to the United Dairy Farmers downtown:  awesome breakfast
 - China One:  good bad Chinese food located next to the Kroger
 - Pita something....located downtown.  I'm pretty sure it's a chain but it's good.  Get the falafel sandwich.
If you're there, I'd make time for Steinkeller, Skippers, Bagel & Deli, Kona and Patterson Cafe.
Places to ignore (in addition to the usual chain fare):  Phan Shin (horrible Chinese), Brick Street (Sysco-tastic), SDS Pizza (dense undercooked pizza), Bruno's Pizza (unless you're drunk)
Hope you enjoy it!
