My husband and I are celebrating our one year anniversary in DC. We are staying at the Renaissance M Street (on New Hampshire Ave NW) and would like a suggestion for a relatively inexpensive place for a special dinner (if such a place exists). We love all types of ethnic food- Indian, Thai, Japanese, Greek, Vietnamese, etc. and especially love local, organic healthy food but we are really open to anything so long as there will be some entree options under $20 and a nice atmosphere. I think if it were up to my husband, we would go to Four Sisters but I'd prefer something a little more "special" for our anniversary. Outdoor seating would be nice and we'd like to be within a short cab ride or walk from our hotel. Thanks in advance for your suggestions!
