There's nothing small about Lumpy's Diner Express. It's not just that its eight-page menu is stocked with a variety of burgers, hot dogs, and other diner favorites—it's that it features several "Big Appetite" challenges, including one that requires diners to devour a burger that weighs more than 4 pounds and is loaded with at least six different toppings.

Lest its diners think that Lumpy's only features heavy meals, it offers healthy choices such as low-fat bison patties, grilled chicken, and protein shots for the milkshakes. An array of theme nights—such as Car and Bike night Mondays—and Betsy Ross look-alike contests round out Lumpy's all-American vibe.
