Perhaps because of the large number of Japanese news reporters and diplomats in Washington, the area has an excellent selection of sushi restaurants, and locals have been known to get into spirited debates over which is best. Here are a few options.

Dupont Circle

In the restaurant and bar-heavy Dupont Circle neighborhood is Sushi Taro, a highly authentic and constantly packed second-floor eatery that is nearly always mentioned in any debate over the best in town. Within easy walking distance of the Dupont Circle metro stop, it offers a wide variety of sush and other Japanese dishes and can frequently be filled with Japanese officials visiting from overseas or those based in D.C. itself. For those who speak a little Japanese, ask for the special menu with more traditional Japanese fare. And if you're seeking a truly authentic experience, ask for one of the tables where you sit on the floor, sans shoes.

Arlington, Va.

Kanpai on Wilson Boulevard has the best sushi in Arlington and some of the most wonderful kitchen and wait staff anywhere. This resturant merits a huge waiting line. Set on a plaza just off of Wilson Boulevard a few blocks up the hill from the Rosslyn Metro, Kanpai sits happily with a yellow awning, a small fish pond on the side and outside seating in good weather. The inside is peaceful and bright with large windows overlooking the plaza. Enjoy! Diners report feeling healthier whenever they eat the Kanpai salad with wonderful fresh tuna, broccoli, avocado and very crisp lettuce.
