maybe if you are very, very hungry, and when you really have nothing else to eat ...
Bob, if French fries are these small sticks of potatoes fried in hot oil, this is indeed extremely popular in France, Belgium, and almost all around Europe ; we call that simply "frites". An anecdote (for fun) : in Belgium, the name of the shop selling frites was "Friture". But for snobistic reasons, despite the fact that Belgian frites were much better, they imitate France, and changed the shop-name to "Friterie"... whith a 50% price increase !!! (exactly as with any "Branding", no?)
