So, I will be stuck in a nasty convention at a Marriott Marina Hotel near the convention center. If I am at the Marriott and don't want to have lunch at the hotel, is there a recommended place within walking distance that is not overpriced, not filled with fanny pack tourists, and has great food?Not picky either on types of food. It could be a fabulous cheeseburger or sandwich, a fresh salad, authentic Mexican, or anything else that is deemed mouthwateringly good. Fancy or hole in the wall is fine. Thanks in advance for any help you can provide.
