Katz's has the best pastrami sandwhich in the world. Everyone must try it. Everyone!
Here's a cool video to get you pumped for dinner. A few things; Katz's has been in NYC for over 125 years and still uses the same recipes. They make their pickles and pastrami in house and they pride themselves on tough new york service. The food is awesome and you'll leave wanting to take a long nap.
Also, this happened at Katz's. One of the greatest movies scenes of all time. You have to watch it before you go.
