hmmm, that triple decker sandwich is my favorite. The last one I had was my second favorite: with corned beef, pastrami, chopped chicken liver, tomato, raw onion, cole slaw, with three slices of fresh rye bread....dill pickle on the side; recommended source for this: Hymie's Deli in Merion PA, fortunately a couple blocks from my home. Check out their hot meat:
