authentic east-coast style sandwich.
Be sure to give give Grand Central Station a try. I love the cheese steak with pastrami. They serve the sandwiches plain and have a station with dozens of condiments that you can put on to make it just the way you want it. Great idea.
The location is hard to find, its near the UPS central hub, but the food certainly makes up for the poor location. If you like authentic east-coast style sandwich shops, You'll like Grand Central Station.
