I've done this more than once. I like San Diego, but compared to LA, it seems to be a wasteland for eating and shopping, fish tacos and a handful of restaurants in La Jolla excepted. Not sure why. Maybe the proximity to LA, and the difference in consumtion patterns makes it unprofitable for high end retail, but don't people like to eat? It's been a while since I've been, though. Maybe it's changed in the past few years.
