Shake Shack is coming in the fall, serving "natural burgers, flat-top dogs, frozen custard, beer, wine and more." (See Grub Street, and Brownstoner.)
That means competition for two smaller establishments a few blocks away: Bark and 67 Burger. At all three, I'm sure, beer costs far less than inside the arena. And Shake Shack will be closer.
