We are a French - Belgian Family, and have been away from Europe for 3 months. This was quite a treat. They make every effort to make it feel like France, and it does, from the greetings in French to the menu. We felt strangely comforted to see so many familiar names on the menu. Of course a Chilean wine was chosen. We had as starters the carpaccio, and as main courses the steak tartare (raw meat, called filet américain in Belgium) and the entrecôte béarnaise. Desert was nougat glacé and café liégeois. Everything was excellent. Service was attentive and effective.
In fact the least French part of the whole experience was the service, which was better than in France. It was somewhat US-like, in the sense that it was fairly fast. But never did I feel rushed.
Some comments here criticize them for being too fast. Personally I prefer this to waiting too long, especially with children. Also note that being fast allows them to fit in more people: we observed couples leaving and new ones coming in. We only got a table by promising to be there by 8 PM. I'm sure our table was filled when we left (about 10 PM).
Price-wise it was reasonable, 70000 pesos for a family of 6 (the children shared a plate, and we had only 2 deserts), or about USD 130. But we all agreed (a rare occurrence) that it was an excellent value.
Overall: feels like France to French people, except that the service is better. Would also rate as an excellent experience if transported to Paris or Brussels.
