Have you tried Vietnamese food? Very similar to Thai, but less heavy on the sauces, generally lighter ingredients, IMO.
Cuban food is one of my favs, of course I grew up on the stuff. I would think you could find some in SD.
Living in New England, I too love seafood, including lobster, shrimp, fish, etc. But I don't like it in the traditional "boil it 'till it's dead and drown it in butter" style. I'd much rather have that lobstah as a fra' diavolo....
