If you’re looking to show off your local knowledge to friends visiting the city, take them to Switzer’s. As they operate from a pop-up cart, you’ll only know where to find these mouth-watering pastrami sandwiches if you follow their Instagram account—you’ll feel like an exclusive member of the club when you figure out where they are. And when you do, get there quick, because Switzer’s is known to sell out of their limited stock fast. Before being served, the pastrami is dry cured for over a week and cooked sous vide (a temperature-controlled style of cooking) for a few more days. Get the tender piece of meat in a basic, classic sandwich, choose from one of the many rotating selection of twists on the dish, including BBQ bits, and pulled pork burgers.
