63 Rokusan Jingisukan grills lamb in Sapporo. It serves lamb loin and lamb ribs along with lamb bacon and lamb tongue, and offers an all-you-can-eat course and unlimited drinks. The basement space has tables where guests face each other and one- and two-person counter seats, and staff check on refills as food and drinks run low. Reservations are common, so walk-in entry is difficult.
