You have a lot of Starbucks in Tokyo.
This one have the particularity to be in front of the Shibuya crossing on the 2nd floor.
It's a pro and a con. This is good because you can sit down and observe the waves of people that go everywhere but the con is the place is not so large and that you are not the only one to want to see this !
There's always a lot of people waiting. It's frustrating.
Another thing, you can't take pictures of people crossing. Everybody do it but sometimes the staff will ask you to stop.
If you can get a seat at the window, this is a good place to watch the intersection in shibuya. If you try to video out the window, staff will ask you to stop. The coffee here is just like any other Starbucks around the world. Get your Grande Mocha Frapa Java chiatto and head upstairs. IF there is a seat with a view, consider yourself lucky. If not, wander the Tsutaya it is connected to and check out obscure or mainstream music.
Perfect place to sit and watch the world's busiest intersection. But if you want to sit anywhere, be prepared to wait. Unlike it's other million locations, this Starbuck's comes with one-size cups and a limited menu due to the sheer volume of customers.
The Starbucks in Shibuya is very convenient just in front of the Train station. The memorial of Atchiko is not so far.
I think, that place is the nicest place to see the famous shibuya intersection.
