Although there are other locations of Danny Meyer's patties 'n' shakes joint around town (including Brooklyn), this is where it all began. Here in Madison Square Park, there's no indoor seating—just snaking outdoor lines. Check the "Shack Cam" from their website to gauge your wait. Fresh Angus beef burgers are ground daily, and a single will run you from $4.60 to $8.80, depending on what you want on it. For a burger on-the-go, they're decidedly tasty. For a few more bucks you can order a double, a stack, or a vegetarian 'Shroom Burger—a super-rich melty Muenster-and-cheddar-stuffed, fried portobello, topped with lettuce, tomato, and Shack sauce. The menu also offers "beef and bird" (chicken) hot dogs, french fries, and a variety of delicious frozen custard desserts, and—of course—shakes!
