Shake Shack ShackBurger

The ShackBurger brings the fast-casual crowd into the fight. Beef, cheese, lettuce, tomato and ShackSauce on a potato bun make for a compact burger with a very different personality from towering old-school contenders like the Whopper. That sets up the real debate: do you reward the burger that feels a little more polished, or the drive-thru monster tied to years of memories? ShackBurger vs. Double-Double is particularly mean because both have intensely loyal followings and deceptively simple builds. Only one gets your vote.
