95% of the food I've eaten from McD's in the past 20+ years is breakfast. I'm an egg mcmuffin man, have been for a long time. The egg white mcmuffin was actually reasonably healthy and my regular order, but they took it off the menu. Their coffee is solid. In the summers, they've often run "$1 any size drink." Not uncommon for us to swing through a drive through and grab a coupla giant iced teas for $2.
As for non-breakfast...a QP with cheese is often...fine. I had mcnuggets for the first time in eons earlier this year (was waiting on a car repair, walked across the street and got some for lunch). Meh. They seem thinner, and half breading. Fries are good for the first 2 minutes if they're fresh. Filet o fish is a perfectly serviceable fish sandwich. I'll eat a McRib every few years out of nostalgia (my dad and I would grab one on our way home from surf fishing when I was a kid - kinda became a thing, I don't know why, because he was a picky messican and usually disliked such junk). And...that's about it. It sure isn't a destination or choice, and if we're going to grab fast food and there are other options, we'll almost always choose something else over McD's.
Except for breakfast. They've kinda mastered the fast food breakfast.
