San Diego Help?

Anyone out there know San Diego? BB and I are going there with the earthling, and we've just realized we may be in big trouble in terms of feeding the earthling. (The first time we were there, I was in the first trimester of pregnancy and we spent half the time searching for food, because there did not appear to be any in San Diego - seriously, people down south, do you just not eat out at all? - and going somewhere with a woman in early pregnancy means you need a LOT of food. Best Beloved had no idea how much I was eating until that trip, and I remember the first morning she watched, horrified, as I ate my entire breakfast, and half of hers, and then two food bars. She told me later that she was genuinely afraid that I might eat her arm next, which was probably a good thing, as she was very diligent about the food search thereafter.)

Anyway. If you know San Diego, I would appreciate recs for:

1. Kid-friendly, vegetarian-friendly places to eat. If they serve earthling-friendly food, that's a plus, but we can work his issues in most restaurants because he's distracted by everything going on around him. (Provided we do not ask him to eat hot dogs. Hot dogs are Just Wrong.)
   
   
2. Kid-friendly places with very fast service. (Mongolian BBQs! Places where you order at a counter! Salad bars! Whatever! Sadly, the earthling will not eat at true fast food places, like McDonald's or Burger King. He judges them.)
   
   
3. Grocery stores that are not Albertson's or Ralph's, where the parent of an earthling could purchase organic produce and all-natural snacks said earthling might actually eat.

We will be staying near Sea World, but are willing to drive to places if they serve food there.
