I'm coming to LA Wednesday--10 days of work. Not sure if I'll have a car for dinner; lunch out impossible. I'm staying at the Hilton Checkers on Grand Ave, and working out of a studio on South Bixel. I'd love recommendations for great cheap to mid-price ethnic--preferably authentic Thai and Mexican, which are a bit scarce in NYC (though improving). And any just plain great local stuff you'd recommend,near either the studio or the hotel. I don't mind a total lack of ambiance, but I'd like to know if that's the deal. Thanks.
