Starbucks Coffee Shinjuku Gyoen is inside Shinjuku Gyoen park, away from the busy streets around Shinjuku Station. Through the full-length windows you can see a large pond and the garden, and you can order an Americano along with bread and cake. Seating inside is limited, so finding a seat takes time after lunch, and you can take your drink out to the benches or grass outside. The park's hours change with the seasons, so the store closes early as well.
