Wagyu Katsu Sandwiches Are Taking Over Instagram | Eater

"A members-only Tokyo eatery originally based in Akasaka that offers a wide range of wagyu cutlet sandwiches across multiple locations; its cutlet-focused outpost in Nakameguro serves sandwiches made from various wagyu cuts (priced roughly from inexpensive ground-beef options to top chateaubriand around $180), using extra-soft white bread and a house sauce that blends Kamebishi soy and Fuji vinegar with a secret mix of spices, plus off-menu soy-wasabi and fermented red-pepper sauces. The operation has explored international expansion, including plans for a butcher shop and U.S. outposts." - Kat Odell
