Langer's Delicatessen-Restaurant shared by @eater says: ""Perennially considered the best pastrami sandwich in the country, Langer’s produces some of the finest deli meats anywhere. Open since 1947, the legendary #19 sandwich is a crowd-pleasing favorite, with hand-sliced pastrami, Swiss cheese, Russian dressing, and coleslaw served between two plush slices of rye bread. It’s a big sandwich that can easily be shared between two people. Don’t sleep on the corned beef or any of the other classic deli plates either because they’re all excellent."" on Postcard
