A club sandwich is a double decker sandwich turkey, bacon, lettuce, tomato and mayonnaise on toasted bread. Most everyone has eaten a club sandwich at one time or another. Every Americana restaurant has a club sandwich on the menu. Seems hard not to like, it doesn’t have anything weird on it like thousand island dressing, sauerkraut, black olives, avocado, just the basics. They even seal the deal with bacon.
