My three favorite burgers in New York are:
Corner Bistro 331 West 4th Street – Greenwich Village
Island Burgers and Shakes 766 9th Avenue – Hell’s Kitchen
Peter Luger’s 178 Broadway – Williamsburg, Brooklyn
warning: Island Burgers and Shakes does not serve french fries. If you are in the mood for just a burger and a shake, it is still highly recommended.
another warning: Peter Luger’s only serves their burger at lunch. It is delicious and very inexpensive. I think it was exactly $5 last time I had it. Considering the price of their steaks (over $30) and the quality of their meat, the hamburger is a true bargain.
