The McDonald's at Yonge and 16th is my go-to place for McDonald's as it's closest to me. Sadly, the drive-thru quality is horrendous. I've had orders given to me that weren't mine and I've ordered items that I didn't end up receiving: you name it, I've experienced it. Once, I asked for my fries to be cooked without salt and instead they gave me cold leftover fries with salt. Did they think I wouldn't notice?
This place is pretty bad. If you want a quick McDonalds fix, but are willing to risk compromising the integrity of your order, then go to this McDonald's.
