I went to Umayano Gakuya, a restaurant located in ITOCiA Yurakucho. Here, you can eat backstage foods and set meals, and is a great place for girls! I ordered the chicken and beef roasted set meal. The beef tongue was thinly cut, so the texture was chewy but juicy. The set meal comes with a grated yam and miso soup, which is also a plus!
