Starbucks Coffee - Marunouchi Oazo sits on the first floor of Marunouchi Oazo, near the Marunouchi north exit of Tokyo Station, and serves coffee, drinks, and brunch desserts. A barista can explain Reserve coffee before you order, and you can pick brunch desserts at the same time. The shop is often nearly full from early morning, and seats inside are limited, so it fills up easily even on weekdays. Benches outside the shop and seating in the shared Oazo space are also available.
