1950s diner fries up fast-food classics 24 hours a day.. In Short Entering the clean, bright interior is like stepping into an "Archie" comic book. Hurrying across white- and black-checkered floors, staff in crisp white shirts and paper hats take orders, polish chrome and shuffle between booths and the full-service counter. Middle-American diner standards dominate the menu--pickle-covered steak burgers, chili cheeseburgers and thick shakes. Healthier options include chicken, chef and taco salads.
