This novel restaurant in Kansas City is a must for kids and big kids alike. It first opened in 1954, but it wasn't until the 1970s, when owner Fritz and his wife Virginia had opened their second location, that it became something special. Due to a labor shortage, Fritz invented a mini train to carry food around the restaurant to his diners. Today, there are three Fritz's restaurants (all in Kansas City, but one over the state line in Missouri), all of which feature train memorabilia. The mini trains still carry burgers to guests, too – much to their enjoyment.
