Mos Burger is a chain restaurant in the Kichijoji Sunroad shopping street in Tokyo that serves hamburgers and french fries. It offers a shrimp katsu burger and a limited-time Tsukimi focaccia, along with standard items such as the cheeseburger. Seating is spread across three floors in a small building, and a sign at the first-floor entrance tells customers to find a seat first. Orders are placed from the table by smartphone and the food is brought to the seat, and the french fries are sometimes under-salted or soggy from being under-fried.
