Oooh. Shake Shack. It's one of those restaurants where people argue if it's the best burger in the city. Quite honestly, the best trait of this restaurant is its locations. The food is great no matter where you are. The Madison Sq. Park location is great when you just want to relax in the park. the UWS location is also great if you just want a quick, cheap bite. But you have a better chance getting a burger in under 5 mins at the UWS location.
