Great restaurants and clubs in the Gaslamp district. The SD zoo and wild animal park are awesome. The air and space museum is weak.
Hit TJ and go to Revolution St. buy a fake rolex, cuban cigars and plenty of Louis Vuitton.
You should go to the Hotel Del Coronado that is a great place to see and learn about the history. It is also a good place to eat and watch the sun go down. the Pac Fleet is stationed there, so drive down toward the piers and look at the ships.
Eat here
The beaches in Del Mar are great, but the water is cold and too much sea weed for me. Check out some of the houses in La Jolla. Big bucks in La Jolla.
