New York does beef better.
Shake Shack’s juicy burgers are made of a blend of genuine Pat LaFrieda brisket, short rib, and sirloin that are delivered fresh daily and griddled to a paragon of crispness. They are unequivocally the best fast-food burger patties on the market. In-N-Out’s burgers are “100% pure beef” and are caked in spices to mask their innate mediocrity.
Not to mention the fact that In-N-Out's fries aren't even that good -- and that you pretty much HAVE to get them animal-style as dictated by the freaky West Coast Internet-dominating hive-mind, and also as dictated by the fact that covering them with other stuff is the only thing that makes them remotely delicious.
Despite all its “secret” menu additions, it still has fewer offerings.
Shake Shack’s menu, in addition to their dope burgers (including an actual vegetarian burger -- take that, In-N-Out grilled cheese!), fresh-cut fries, shakes, and sodas, also has hot dogs, frozen custard ice cream, concretes (you can even design your own), beer, wine, and an entire section devoted to treats for its customers’ dogs. Who’s a good burger joint? You are!
