I'm going to San Diego on business and, finally, I'm going without the family--so I can try some new things. What do the locals eat? I want mid-range and less expensive, with maybe one nicer restaurant. I like all cuisines, but would love to know the nontourist places. Outside of that place in Old Town with the giant margaritas (who cares about the food ;-) ) I haven't a clue. Help!
