Buns Bar in New York City is primarily known for its burgers and sliders, but it is through dessert that the eatery is truly famous.

It has become a social media sensation due to its ridiculous milkshakes, highlighted on its Instagram bio for being “The Biggest Shakes In The World.”  Not only are they big, but they are elaborate and decadent also.

Just one look at the restaurant’s Instagram page reveals dozens of sugar-packed treats. The process behind making them is fascinating.
