I moved to Highland Park from Skokie in 1979, and have lived in HP for most of my life since then, and this thread is bringing it all back for me as well.
I remember Victoria Station with their train cars (big deal to a kid then), Peacock Palace was heaven for me, Strike and Spare was another favorite hangout, and of course Edens I and II. I remember going to see Raiders of The Lost Ark in 1981-82 there, arriving in the middle of the movie, watching it to the end, then watching it in it's entirety at the next showing. We had seen it before, and would see it many more times in the theater. Movies were a big deal then!
I miss that old Arby's. In the space behind it where CompUSA is was a Silo, and I think a Highland Appliances before that. Don't forget Herman's Sporting Goods.
Timber's, in case you didn't know, also closed recently.
Another cursed location is where Prairie Grass Cafe is now (and doing well) - next to Fast Signs. Previously it was a Stefani's, Stonefish Grill (I think), among others.
There's a Morton's Steak House next to Ron of Japan now and they are finally building a lot more stuff on the west side of the street between Dundee and the Tollway Spur.
Forty One North could have been so much better if they actually cared. The motherlode burger and cottage fries did harken back to the Claim Company, but they had little things that got worse. One thing I noticed everytime was dirty sliverware and glasses, ketchup being refilled with god knows what kind of ketchup in a Heinz bottle (now a pet peeve of mine - I try to ask for a brand new, unopened bottle wherever I go out IF I suspect the restaurant of not only reusing an old bottle, but filling it with something other than Heinz). I hate restaurant owners who pull this crap. Don't they eat there too? When I worked in restaurants I either cooked or served ever single thing as if it was for me!
Now don't get all excited about this, but my mom said she heard the Claim Company is coming back.

She usually hears it from other friends of hers that almost always can never be depended on for anything. Take it as a wild rumor please!
