Quite fast service for lunchtime, "plat du jour" choice, friendly service... That's it.
They are lucky to be placed in an area where there is not much choice at lunchtime... "Plats du jour" could well be "plats de l'année" as it seems unchanging over the weeks. Very random food quality. If you happen to be in the area (U.N canton of Geneva :) and if you have no idea where to go, you can give it a try in order not to starve.
