This restaurant serves fresh and delicious premium wagyu (Japanese beef) at decent price. They serve fresh beef using rock salt, but not using sauce. Variety of beef menus even you have beef tongue Sushi. There is another branch 1 min walk from here, but I prefer this branch since we can enjoy meal in a exclusive room.
