Somewhat, but I think it's because I've grown up and my expectations of what constitutes decent food has therefore matured. No more a very vaguely meat-flavoured grey disc between two bits of stale bread with something that resembles ketchup and/or tartare on it...
The fries are still good, though they still tend to be a bit limp.
TBH, McDonalds has registered as "food of last resort" for me since at least the turn of the millennium, it's always been tinged with disappointment when it arrives, and the main benefit is that it's affordable (certainly not "cheap"), usually quite available, and it does satiate gnawing hunger and thirst in short order. Plus you can roll up at the drive thru in off peak hours and be back on the road, attempting to unwrap and handle a burger with one hand at 70+ mph within about three minutes flat. Great if you're in a rush. But it's not exactly gourmet, or even hugely enjoyable - certainly not "treat" status like it was when I was a more easily pleased kid (who figured alphabetti spaghetti with mini frankfurters in it was the absolute pinnacle of human achievement).
Burger king is somewhat better. They at least seem to make some kind of effort to retain flavour and moisture within their products. Last time I had one, it was about the same as the first time - perfectly acceptable, though not really any better than a supermarket hamburger, cooked in a domestic grill and served in a supermarket bun. KFC is an actual guilty pleasure, but I very, very rarely have it as I can justify neither the cost nor the mess it makes of the car, hence I can't speak for how it's changed recently.
However, being a true Brit, I haven't skimped so much on the chips and curries. Fish and chips has maintained its usual standard, though there doesn't seem to be as much part-cooked, fish-juice-infused slimy batter on the inside of the crispy shell as there used to be (a true guilty pleasure, which I mourn

), and remains better than anything I could hope to create in my home kitchen. And the most recent non-home-cooked curry I had was equal to the best I've ever tasted. Though the same can't be said for the curry sauce that you can get on chips - it seems to have fallen from it's once lofty peak.
Captcha: Clear blue water. Think it's trying to tell us something?
