Philly Cheesesteak -- Philadelphia, Pennsylvania
The exact provenance of this sandwich shop staple is hotly contested, but few doubt that it had its roots in Philadelphia, nearly 100 years ago. The ingredients are modest -- cheese, sliced steak and bread will do -- but the taste is out of this world, particularly if you find an authentic sandwich shop willing to take the time to actually cook the meat rather than just reheat it.

Deep Dish Pizza -- Chicago, Illinois
While New Yorkers and Chicagoans rage on over which city has the better pizza, we get to enjoy the best of both worlds. Chicago’s famous deep-dish pizza, with crusts up to 3 inches tall, was invented at Pizzeria Uno in 1943, and has been helping to quell hunger pangs and fuel city-vs.-city feuds for over 70 years. Not bad.

Crab Cakes -- Baltimore, Maryland
You may have had crab cakes before. You may love crab cakes. But if you haven’t had Maryland crab cakes, you haven’t really had crab cakes. Crab has been a staple food of Baltimore for as long as there has been a Baltimore.
