Big wooden table inside, some table outside when it is sunny (on the sidewalk of course, but the street is not toο noisy so it is okay) and bottles of wine inside on every wall!
Whatever wine you want, to stay or to go, they probably have it. And if you don’t know what to have, then just ask them to pick one for you (they serve by the glass). I’ve always had great surprises. Their wines are natural or organic which is also a plus for the place.
To go with the wine, in the evening, they have ham and cheese plates, terrine of all kind of poultry, foie gras also. All comes with good bread (a good ham and cheese plate with bad bread is the worst).
Of course looking for a wine bar in Paris is not difficult but I like to have one good spot near my place where I know I will find good wine served by nice people and more important where there is no pressure: no people too dressed up and not too crowded! And Les Caves de Prague is all that!
