if you're in chinatown, why don't you get chinese food? oh well, if you want japanese food, ginza is a well known japanese restaurant with a few locations (others in boston, brookline). the waitresses wear awesome kimonos and those cute japanese sandal shoes. it sets the atmosphere to be like you're in japan. the food is good too, but kinda pricey (because you're in chinatown). the sushi is fresh and the rice plates are portioned so you won't have any left overs.
