My roommate has a friend coming into town and was hoping to go to dinner somewhere fun and reasonably priced. I would give Matchbox and 2 Amy's as examples of what we're looking for (did 2 Amy's last weekend, and we'd do Matchbox but we're a little weary of no reservations for a group on a Saturday night). We've done a group thing at Zengo before too but weren't floored, so want to try something different.
Any suggestions? Location isn't a big issue (DC or NoVA), nor a particular type of cuisine.
