Koiwainojo Tokyo Marunouchi is a meat-focused Western restaurant on the fifth floor of the Marunouchi Building, directly in front of Tokyo Station. It serves hamburgers, steaks, and beef stroganoff made with ingredients from Koiwai Farm, and soft-serve ice cream is available at the end of the meal. The restaurant opens at 11 a.m. and fills up around noon, and a lunch reservation can get you a seat in a semi-private room. Seats are close together and indoor lighting reflects off the windows, so the Tokyo Station night view appears blurry.
