They taste good (all ingredients not clearly stated), are consistent (careful control of manufacturing), are served hot (small batches in the fryer), and are surprisingly long--a 10 cm specimen is typical.

Personally, I don't like McDonalds french fries that much: at least where I ate it, it was always over-salted (which I assumed was an intentional trick to get consumers to buy more soft drinks).
