I would recommend Sea World, at least its something different from what we have here. The Orca (killer whale) show is amazing. You can be adventurous & sit in the front soak zones

I took a guided tour and they brought us to the back areas of the park which was quite nice.
As some said, La Jolla (pronounced as Hoya) is a nice place. The walk at night is nice.
For me, whale watching sounded exciting but after a 1.5 hour boat ride out, we managed to see some whale fins protruding 30cm above the water. Nothing like the photos in the brochure of gigantic fins extending beyond the height of the boat. Didn't enjoy it.
Food?
Definitely authentic Mexican food. Order the Large Margarita. It comes in a cup the size of a huge fish bowl.
I've not tried many restaurants but one of the ones i like is a chain called "Claim Jumpers". Its a gold mining theme type of restaurant. Something different too. What differentiates this place is the size of the servings - huge! A full rack of ribs is about40cm long. A slice of choc cake is really one slice, but about 7 inch thick
