The renowned Katz's Delicatessen in New York City is famous for its perfect pastrami that has delighted the people of the city since 1888. I've never been there, but I'm salivating over the Reuben sandwich on the menu.
Michael Palan of The Takeout ventured to Kith Treats, an ice cream shop, there upon hearing reports that it's offering a sundae flavored with the tastes of Katz's.
The Dilluxe has pickled, chocolate, rye croutons, and vanilla ice cream mixed with pastrami rub and mustard. Palan shies away from definitive approval of the mixture, but does affirm that the treat is reminiscent of Katz's.
