Even on a tight schedule, Katz's Delicatessen earns the hours.
Allow 45 min–1 hour incl. queue.
A cavernous, ticket-in-hand, cash-grabbing institution where a guy behind the counter slices your pastrami and slips you a taste while you wait. Electric for first-timers and pilgrims; wrong for anyone wanting a quiet, leisurely sit-down meal.
