The predecessor of Midorikawa Private Banquet was Midorikawa Sushi, named after the invited Japanese chef Midorikawa Yoshiki, Midorikawa Sushi opened in 2009 and was quite popular in the Beijing Japanese restaurant circle at the time. Later, Midorikawa Sushi in Sanlitun was renamed Midorikawa Private Banquet, which specializes in authentic Japanese cuisine such as sushi and sashimi, and the chef is still Midorikawa Yoshiki, and it is popular among diners because of its warm hospitality and modesty. Although Midorikawa Private Banquet is positioned as a mid-to-high-end restaurant that produces set Japanese food, its pricing is popular and accepted by most diners. The set meal of the Green River private banquet is about 500 yuan per person, and the quality of the ingredients can be maintained at a high level, and the menu is updated from time to time.
