Since in 1963, this classic diner has been serving up a legendary classic hamburger. In fact, George Motz's "Hamburger America" lists Pie 'N Burger as one of the best burger joints in the whole country. This little Pasadena diner has been wowing food critics for decades – and for good reason. Their cheeseburger is a thing of beauty, a quarter-pound patty of fresh beef fried up on a griddle, then piled high with pickles, American cheese and a large slab of iceberg lettuce. Then their "secret sauce" (a house-made Thousand Island dressing) is added, the whole thing is wrapped in white paper and ready to delight. Make sure to add an order of crispy fries and leave room for a piece of their wonderful homemade pie, just like Grandma used to make back in the day.
