Diners, Drive-ins and Dives: Blast from the Past

Guy Fieri checks out some joints where things are still done the old-fashioned way. In Oklahoma City, a steak house that's been serving the same steaks, desserts and even salad dressing for more than 80 years; In Los Angeles, a 1940s diner brought back to life by a chef doing mac and cheese, fried catfish, and donuts her way; And in Boston, three brothers carry on 40-year-old family tradition -- making clam chowder like Dad -- and chipotle/pastrami sandwiches.
