Whitecrown Seinikuten Nakasu is a specialty restaurant in Nishinakasu, Fukuoka, serving black-haired wagyu steak and yuke carpaccio. The chef grills the meat on a teppan in front of you, serves it rare, and cooks it further to your preferred doneness. The steak comes in two cuts with salad, soup, and rice, and the rice can be refilled. Service is not smooth, with staff who explain poorly and rush payment.
