Well, I popped in Chickies Mark III on Pulaski. It's changed a bit, although I don't think it's a bad beef. It's not quite what I remember Chickies to be, but unlike the last time I visited Chickie's (under the second set of owners), the texture of the beef reminded me of the original Chickie's more. The original Chickie's has always had a sliced-but-falling apart texture to it, which is what my beef today was like. The gravy wasn't overly spiced or anything like that, which is the way I like it. It didn't seem quite as beefy as I remember it being, but it's been, what, four years or so since the original Chickie's has been gone? The mouthfeel of the sandwich was also a bit on the greasy side, although that may be because of the next item: the giardinera. No more distinctive peppers & celery giardiniera with that wonderful crunch. This was a more standard giardiniera with carrots, peppers, celery, (although I didn't notice any cauliflower or other vegetables). I should have asked for it on the side to get a better look at it.
The hot dogs were a disappointment, though. No longer natural casings. I went to Chickie's just as often for their hot dogs, so this is a disappointment for me, as it's hard to find a natural casing stand in my neck of the woods. I got into a brief conversation with the guy working the food line who said the problem with the natural casing hot dogs is that snap they have. To which I replied, "but that's my favorite part!" Well, it seems the neighborhoods tastes change, and he said I was the first person to remark on it. That's not surprising, as I doubt most people even pay attention or know there's a difference.
Didn't get a chance to try the fries. I had already blown my caloric allotment for the day.
Still, I would go back for the beef. I'd encourage others to try it and see how it compares with their memories. My recollection of Chickies Mark II was that it was nothing like the original Chickies, while others here had more positive experiences with it. This one I'd say the beef reminds me more of the original Chickies, but the gravy is a bit different and the giardiniera is definitely different.
