People Are Addicted to Waiting In Line for Shake Shack

Shake Shack fans started lining up today at 7:30 a.m. for the burger chain's 10th anniversary specials. Today, Danny Meyer's Madison Square Park restaurant is serving a burger from Daniel Humm made with gruyere cheese, bacon, celery relish, truffle mayo, and fresh shaved black truffle — presumably from Australia — for $8.50 a pop. Shack Shack is also offering "pay what you like" Shack-Cago Dogs, and birthday cake slices from Dominique Ansel.

A tipster sent in this photo of the line around 10 a.m. today, and it looks like several hundred more people have joined the queue since this picture was taken. It's not quite as long as the line for David Chang's burger earlier this week, but it's pretty close. For those Shack fanatics out there, here are pictures of the burger, the birthday cake, a surprise from EMP, and the original hot dog stand iteration of Shake Shack from 2004, plus one more pic of that nutso line:
