How long do you have to wait in line for a Shake Shack burger? 1 hour.
 
Was it worth it? Yeah.
 

CLOCKWISE FROM TOP LEFT: (1) My order: burger, fries and a Liberty Shell brick. (2) The mushroom burger was amazing, crispy and hearty. I didn’t miss the meat at all. (3) The food buzzer when your order is ready. (4) The second line inside the store.
