Mmmmmm. When I was twelve and thirteen, my friends and I used to go to Cooley's Cupboards in Evanston, Illinois. French fries, catsup (ketchup? I don't remember which name), cherry cokes from the fountain, and, I think, a jukebox at the table (may be wrong on that).
It didn't make me fat; I was a skinny kid.
I'm for McD's making some healthier choices available. Don't know that this recent change is an improvement. I guess good that it is available, but being able to just have the apples or the fries should/could be too. On whole wheat buns, good idea, but then again, I'd prefer choice. I have grown in the past few years to like a lot of whole grain breads (while still liking some hearthbread type white flour breads), but I still dislike miserable whole wheat buns as much as I dislike miserable spongy white bread buns. The level of improvement nutritionally from miserable white bread to miserable whole wheat bread is questionable to me, but probably somewhat for the better.
My bias: We had a McD at the end of out street for decades, and I stopped going there early on. Got even more irritated when they started to invade Rome, from my crabby point of view. Well, mine, and the guy who started the Slow Food movement,
Carlo Petrini. However, I am still a sucker for Burger King's (basically crap) fish sandwiches, fries, and a coke. Go figure...
