Shake Shack has one of the best breakfast menus in fast food

Shake Shack knows how to make burgers fairly well, and chicken extremely well, but what about breakfast?

Only six of the chain's 110 locations worldwide serve breakfast - and luckily for Business Insider, four of them are in New York City.

We went to the closest one at Fulton Center - the others are at JFK Airport, Grand Central Station, and Penn Station - to find out if the famous burger shack knows how to serve up breakfast, too.
