Kobe Beef Kaiseki 511 was one of the restaurants on my must try before leaving Japan or don't leave Japan at all. It's in an alley way and the decor is very modern and contemporary.
Imafuku is located in an odd spot in Minato, Tokyo. It's right next to a bunch of different apartment complex and an oddly quiet area for a sukiyaki spot.
Yazawa Beverly Hills is apart of a restaurant chain that serves quality A5 Japanese Wagyu. It's sister restaurant is Imafuku Shabu Shabu & Sukiyaki and happens to have one Michelin star.
