The fries in France and Belgium taste like potatoes, I kid you not. Here they taste like grease and salt, I almost never find good fries in the States. I can find good onion rings, and when good, they need only salt. I put ketchup on fries here to give them some kind of flavor.
Usually, I just avoid them if possible. I think here they often are made out of polydimethylbatshoot.
