50 Hours in Tokyo: Shake and Shack in Line

I expected it's probably going to be a crowd when I decided to check out Shake Shack, the first Asia outlet of the New York-based burger joint, inside Meiji Jingu Gaien Park on a beautiful Sunday afternoon, but I definitely didn't expect by the time I got there at 1pm, the waiting line got to 300 people deep, stretching outside the restaurant and well into the tree-lined path that ran along the park.
