There was Dans Le Noir in New York City for dining in the dark, Bors Hede Inne in Carnation, Washington, for an authentic medieval dining experience, Moto in Chicago for culinary gastronomy, and Ghetto Gourmet for bringing a gourmet chef to cook food in your house. And then the restaurant that you likely haven't been to unless you have a 5-year-old in tow or were 5 yourself.
Here's Maxim's take on Fritz's:
Unlike people, who require things like money and feelings, trains will be your friends and/or servers for free, which is why the Fritz Railroad Restaurant in Kansas City employs the latter. Instead of blundering, babbling humans to take your order and bring your food, you simply call the kitchen (we can only assume the person taking the orders calls him/herself the Conductor) and place your order on an old-timey telephone.Then, without any interruption from nosey humans, a happy little obedient train will scoot along the intricate rail system to deliver your food, then leave without telling you how to experience your food with the ever-intrusive, "Enjoy!"
Fat City has written lovingly before about Fritz's Gen Dare (the hash brown topped burger that is worth, at least, a drive-through visit), so we're all aboard on this one.
