The dim sum here is fairly average, but there's a lot of it! Some 51 varieties, including 14 desserts, and all you can eat at lunchtime and all day weekends. The decor is modern and attractive, and non-smoking seats are provided. Y3200 at lunchtime, but tea is extra (from Y800); Y3800 for weekend dinners. There's also a regular menu, and late-night hours on Thursday, Friday, and Saturday nights.
Roppongi 6-10-2, Roppongi Hills Hillside 2F. Open 11am-10:30pm (LO; -3am Thu-Sat) daily.
