JG Melon [1291 Third Avenue, New York; Menu]
This Upper East Side institution is always mobbed around dinner time, but if you really want to eat there, it is open until 4 am every night, so you should have plenty of chances to feed your cravings. And this is a good idea because the burgers here are juicy, delicious, and among the best in New York. There's a reason that people come here from far and wide. Finally, I would highly recommend ordering the fries. They are cottage fries and they are awesome.
