We finally had a Shake Shack burger and it lived up to the hype.
It is a well seasoned patty sitting on a super soft and buttery bun with lettuce, tomato, cheese, and some kind of special sauce.
Shake Shack is an institution in Madison Sq. Park. There are always huge lines, everyone waiting for burgers, shakes, and fries. We never felt a burger was worth a 45 minute wait - but now there is a Shake Shake outpost in the new Mets baseball stadium, CitiField.
The burgers are just $1 more and if you wait until about the 7th inning there is about a 5 minutes line. They are amazing! They are the first burger that is crave-worthy, similar to In-N-Out.
It was a little cool out still when we went to CitiField, so we didn't try the shakes - maybe next visit.
Anyway, I would definitely consider waiting in line at Madison Sq. Park for the burger - it was just that good!
