Agreed on downtown San Diego. But there are tons of other good areas in San Diego. Old Town has great places to eat like Casa de Pico and La Pinata. Hillcrest has lots of culture and I'd recommend the Park House Eatery. Pacific Beach has some great crusty hang outs and bars. La Jolla is beautiful. And you have to go to the big tourist attractions at least once like the San Diego Zoo and Sea World.
