I love seasoned fries. Our Arby's went out of business (opened and closed in less than a year) and they used to have awesome ones. Now, I'm forced to buy them and cook em myself. They're not as good though. I eat them plain, but my kids use ketchup.
We usually get fries at Mickey Dees though. If we go thru the drive thru, we'll order a large and all of us eat them on the way home. They're gross once they get cold, so anything that's left by the time we get home is usually tossed into the garbage, or fed to the dog.
Once in awhile I'll make homemade french fries and we use ketchup on those.
I've never tried Wendy's. Looks like I'll be trying them on out next trip.
When we eat fast food, we do the circuit. Burgers and fries from Mickey Dees, onion rings and chicken tenders from Burger King and Chili and Frosty's from Wendys.
