I'd love to get some tips for good and cheap eats in DC. I'm staying at the Embassy Suites - Convention Center w/o a car and the group has some pretty non-adventurous eaters. We'll be spending one day on the Mall and I've heard good things about the restaurant in the American Indian museum - any other suggestions? We'll also be going to the zoo and could use a lunch suggestion. I've read about Open City but it's getting mixed reviews. Would also like ideas for unique / special / historic bars - not clubs. My husband is into craft beers and unique scotch. Thanks in advance!
