I will second (third, fourth?) the recommedation for Makoto. Not only is the food excellent, but the service is impeccable. The waiters always address you by name (e.g., Would you like more sake, Ms. Lee?) I highly highly recommend sitting at the bar so that you can watch the show. And try to make a reservation for the second seating so that you aren't rushed (Makoto is almost always fully booked, so you have to make reservations in advance.) I respectfully disagree with this. Having learned to love sushi in Boston (and eaten at Ginza--both locations--many many times) and having lived in DC for four years, I think many places in DC are as good as the ones in Boston. Granted, I've only been to Sushi-Ko on your list. Perhaps try some of these: Sushi Taro (Dupont Circle), Uni (Dupont Circle) Kaz Sushi Bistro(which others have mentioned). Good luck! And count your blessings...I don't get any above-average sushi where I am now...or even average sushi...it's too frightening. morda PS Sometimes Kaz does an entire blowfish [er, make that puffer fish--well, fugu anyway] menu...I never managed to make it there for that. Anyone ever try it?
