I too was an occasional visitor to the Niles Arthur Treacher's location. It was quite the adventure, for a couple of reasons. First off, there was the exotic departure from the usual suspects like McDonald's, BK, Jack In The Box, etc. I mean, come on, Fish & Chips? Very European for a high school kid with keys to the Chevy Impala.
Secondly, there was the location. For a boy from Morton Grove, anything west of Milwaukee Avenue was The Wilderness. There were rumors you would fall off the edge of the Earth if you drove further than the McDonald's at Milwaukee and Oakton. Walk to the western edge of Golf Mill Mall parking lot and stare down into the abyss.
IIRC, the Chips were unique in their shape and consistency. I'm guessing mashed potatoes were squirted out of a tube to create the eight pointed star shape. Nobody knew about fresh cut Fries back then, so deep fried, artificially shaped mashed potatoes weren't an abomination. Plus, they were pretty good. All those ridges made for some nice texture and flavor.
Tyrgyzistan, FWIW, I know of two restaurants located in old LJS buildings. The first is a very nice Thai joint called Tuptim, located in Ann Arbor, Michigan. I've been there several times and enjoyed the food quite a bit. The outside is the only indication of its origin. The inside has nothing to do with LJS or any other fast food restaurant's design.
The second one is just a few blocks from my home in Des Plaines. Charcoal Delights is on Oakton, just west of Lee/Mannheim Rd. Given a choice, based on quality and general desirability, I'd sooner drive for Thai food in Ann Arbor than the Hot Dogs and Sysco crinkle cuts two minutes away.
