The Best Jewish Deli in Philly. I am a New Yorker by birth and upbringing-until I ate at Famous 4th Street, I had not experienced the real deal in Philadelphia. Best bagels and lox, and best corned beef, pastrami, etc. anywhere in the region outside of New York. Gigantic sandwiches-nobody could eat a whole one in one sitting! From pickles to rugelach a wonderful eating experience-the service is great too!
