Many of the rest stops along the motorway in France have shops. If there is one brand of shop, that brand (i.e. Autogrill) will be listed under the picture of a knife and fork on the road sign alerting one to the presence of a restaurant there.
One rest stop had the phrase "4 pentes" under there instead. Clearly, it must mean that there are four different brands at that rest stop. But pentes literally means "slopes". So what *exactly* are pentes in this case? Kiosks? Buildings? Brands? Company that have hung out their shingles there, so to speak?
