The restaurant is known for its long lines (so much so that they've set up a webcam at the New York location so you can "check the line to plan your time.")
We also foresee that Shake Shack will be a big hit with BASIS students (the new charter school opening its doors to students on August 27th on 8th between D and E). Compounded with tourists, it could certainly get crazy. But welcome to the neighborhood!
UPDATED 8/8 4:30p to reflect that Shake Shack will be in the Spy Museum Cafe and not Zola.
