Another unique feature of nostalgic eateries, I've discovered, is they often make their own root beer. It's something I love about The Port Drive-In in Chesterton, Indiana.
The menu includes classic far like burgers and hot dogs and shakes, but if you make a stop, don't pass up their home brewed root beer served up one of those cold, heavy glass mugs!
And if you really want to complete the experience, follow up your meal with a movie at the 49 Drive In, a classic outdoor drive in movie theatre in nearby Valparaiso.
