Double SmokeShack burger from Shake Shack Madison Square Park. This is one of the better “specials” Shake Shack has offered… applewood smoked bacon and a cherry pepper relish are added to the regular Shack Burger with great results. It’s spicier than I expected, which was a very pleasant surprise. If you’ve never been to the Shack, don’t go and get this. But, if you go all the time and want a change or a tasty, spicy, smoky burger, go for it while it lasts!
