Located at the west exit of Shinjuku, "Shinjuku Yakiniku Gyutan no Lemon Sohonten" is a popular yakiniku restaurant that serves extra thick cuts of beef tongue, with the motto "Thick cuts are the best!". The specialty "Kiwami" steak, made with the rare, top-quality "tongue part" that can only be obtained from a small amount of a cow, is known for its tenderness and juiciness, attracting many gourmets. Its popularity is not limited to Japan, and the restaurant has opened stores in Osaka and Asakusa. The signature "Kiwami" steak is made by cutting the tender and precious "tongue part" into extra thick slices, grilling the surface until crispy over high-quality binchotan charcoal, and then slowly cooking it through to the center, resulting in the best possible condition. Another popular menu item is the thick-cut beef tongue steak and A5 Kuroge Wagyu beef zabuton, served sukiyaki-style. These dishes are made to bring out the best in the quality of the ingredients, as well as the careful handiwork of the chefs.

The set meals come with fluffy and delicious rice, made from rice carefully selected by a long-established rice shop in Kyoto and cooked in a large pot inside the restaurant. Another attraction is that you can enjoy a variety of beef tongue dishes, including beef tongue soup, salad, grated yam, beef tongue curry, and beef tongue miso. It is so popular that it is crowded with customers every day and reservations are recommended.
