Have I talked about Katz's Deli yet? Of course I have. It's one of my favorite places in NYC and so good I think it deserves to get mentioned again. It's just a no frills, down and dirty institution for incredible food like their famous pastrami sandwich.
Mr. T is a purist just pastrami on white bread for him but I prefer mine in Reuban form...
