Osteria arcobaleno is a small restaurant in Sapporo that serves Italian food and wine. Its main dishes are genovese with shrimp and skewers of Sakura-hime chicken and Ezo deer, and the genovese is portioned out one serving at a time. There is counter seating and tables for two, four, and six, and lunch service runs about once a month, so reservations are made early via LINE. Because the space is small, the atmosphere and comfort vary depending on the mix of customers.
