So... the sour cream here doesnt taste 'normal' and the steaks aren't cooked properly here? I havent found that to be true, speaking only for myself, of course.
But... i totally agree about the Mexican fiesta. It's easy to find Mexican food here, but very difficult to find really *good* Mexican food here, made to authentic recipes.
You might consider going out for a Chinese one last time too... the Chinese food here is different... not as spicy and you might have trouble finding some of your favourite dishes (they might be called something different here). Pot Stickers!! That's something i have never seen here! I have tried various types of Chinese dumplings, but so far (Im still searching!) they're not the same as the pot stickers i used to know and love back in California.
