Am sorry Doc, but I disagree. The concierge would only recommend safe places, places that they think the majority of the traveling public would enjoy. Here in Paris for example the GV would recommend (locally Chez Andre, or Chez Francis) they serve mediocre traditional french food. Nothing exiting in their menu. But it pleases the traveler. I once asked the 4S in NY why they do that and the answer it is basic food.

And it is tricky the restaurant that is busy, it has to be busy with the locals. And depending on the area as well. I went to a resto Volney that has been touted for its food, it was busy (lots of biz people, it is in a biz area) but I really didn't find it THAT interesting. Now down the street from me is a great little bistro that yes is full of tourist but locals as well. So be wise.

As for all the reviews, I really don't follow them, since I don't know if we have the same taste. I go by friends recommendations. Here in Europe people travel internationally a lot. So you get some good advice.
