Located south of the heart of Tokyo, Shinagawa Station is a nice alternative to Tokyo Station for people traveling on the Shinkansen. While it's a large station, it's nowhere near the insanity of Tokyo Station, making it much easier to find where you need to be. From here, you can catch a train to Kyoto or any of the other stops on the shinkansen. There's also a decent food selection, including a Dean & Deluca.
stop by the dean and deluca if you're missing home
