Planning on going to Langer's for the first time soon. I had the best pastrami sandwich of my life at Katz Deli in NYC last summer. What's my ordering strategy here? Plain pastrami or should I try it with some toppings? I'm thinking of plain to keep the comparison pure and based on other posts will definitely ask for it hand cut. Probably will share 1/2 sandwich, what sides are especially good?
