Since launching in Madison Square Park in 2004, Shake Shack has become, to put it mildly, a big deal. So big, in fact, that the Danny Meyer-led chain is launching its 100th location next Tuesday, August 16th, at Boston's Seaport. But New Englanders aren't the only ones celebrating.
Between 10:30am and noon on Tuesday, the first 100 diners at every Shack location worldwide (save for stadiums and ballparks) will receive a free single ShackBurger. Burger for breakfast? Don't mind if we do.
