You obviously had a different experience than I did, but moving from San Francisco, which is legendary for Chinese and Thai food, LA's Asian cuisine just tasted generic to me. A little south of LA towards Torrence there is few really nice Japanese places like Musha.
LA (and NYC) have much better and more diverse Japanese and Korean offerings than are available in SF.
Tough to choose between SF and LA Thai food. NYC doesn't come close at all.
I've gotten really tired of Chinese cuisine, for the most part. I still have my favorite overly-lit late night Chinese seafood joint in SF and made the occasional dim sum stop, and Mission Chinese is certainly an interesting take (though I couldn't see myself eating there regularly - interestingly enough they're opening a branch in NYC soon). I'm probably more interested in exploring some of the regional Chinese cuisines more closely. Lately I've been on a bigger Japanese kick since I have so many more options available now.
