The sign is down and the doors are locked, but is Patty Burger closed for good? That's the big question after Time Out's Julia Kramer tweeted a picture of the burger joint's storefront on 72 E. Adams looking very empty. On Facebook, Patty Burger admitted closing on Sunday, but also added that it will be "back soon." What's that mean? We were told that the owner has "definitely not ruled out opening a new location," but that nothing has been decided. Either way, this looks like sad news for burger lovers in the area.
