Philly chowhound headed to LA for the first time for a business trip. Staying at the Omni downtown and would like some recommendations for dinner. Interest in all types of food - especially local favorites (think things I can't get on the East coast), some good sushi (i think little tokyo is within walking distance), and anything else that one shouldn't miss when in LA. Price wise nothing over the top, but would like to experience great LA food. Thanks!
