There's nothing like a great hamburger. Finding a great burger joint is a happy revelation in most towns, and the locals are always willing to make a suggestion.
Even more fun is when you find it yourself, simply by wandering around.
The aptly named Joy Burger Bar, in Manhattan's upper East Side (East Harlem) is just such a place.
(And yes, I get the irony that the above doesn't actually show a burger. Cest la vie!)
