From dealing with high rents to competing with new business fads, New York institutions can be hard to come by these days. Murray?s Sturgeon Shop, however, curbs that trend and keeps to an old-school tradition of devoted customer service and attention to detail in its artfully plated deli spreads. Since 1946, the Zagat-rated eatery?which also garnered nods from New York Magazine?has stocked products made from its namesake fish, such as smoked sturgeon or caviar. Alaskan salmon, whitefish, and lox complement kosher deli meats such as corned beef and pastrami. To cater parties or Tamagotchi-addiction interventions, the shop delivers ready-to-eat soups, salads, imported cheeses, and indulgent desserts such as old-fashioned crumb cake and rugelach by the pound.
