Richard's Drive-In Car-feterias

Back in the 1950s and early/mid '60s, there were, in the Chicago area, several units of a drive-in restaurant chain called Richard's Drive-In Car-feterias. I specifically remember two locations; 87th St. and Stony Island Ave. in Chicago and W. 95th St. in or near Evergreen Park. There were others but I don't know their locations. I also remember a catchy radio jingle around 1960 or '61. The chain had restaurants both in the Midwest and on the East Coast, as Michael Karl Witzel's book The American Drive-In features a photo of a Richard's located in Cambridge MA circa 1957. The one in the photo matches my memories exactly, right down to the logo ( boy and girl twins munching on their double-deck "Twinburgers". ) My family ate at the Stony Island location a few times, and I remember the Twinburgers as being very similar to a Big Mac, only MUCH better. I'm very eager to learn more about this fond childhood memory; does anyone besides me remember Richard's? 

As a kid the best burger I ever remember was at A&W.  The Teen Burger.  The combo of raw onion bacon and cheddar was a first for me.  Its never been equaled, that first taste except maybe my first whopper in 64.

Can I possibly be the only one on this site that remembers Richard's? It was a good sized multi-state operation that was around for quite a few years. Somebody besides me must have memories of those tasty Twinburgers. Anybody?....  

We moved to Lincolnwood in 1955. From Devon to Crawford, along Lincoln Avenue, there were four locations that served burgers: Henry's Drive-In, Richard's Drive-In Carfeteria, Jalin's Restaurant, and Howard Johnson's. Henry's served the best burgers, fries, and pies, Jalin's served the best malts, Howard Johnson's served the best ice cream, and Richard's went out of business.

There must have also been at least one in Detroit, since it is mentioned on this website: http://consciouswords.com/afd/Art/60557/304/Remembering-Detroit-The-Old-Days-Part-2.html
