I am surprised by all the bad reviews for this pretty great and unique restaurant. I have gone to Les Enfants Terribles on multiple occasions: brunch inside, brunch on the terrasse, drinks...and have found it to be great in a consistent manner throughout these visits.
First of all, let me highlight one point people seem to forget: the prices are not any higher than if this restaurant was at the street level (!) Have you ever been to a restaurant up in the sky that did not charge you three times the amount you would have paid otherwise? The prices are reasonable for the food you're getting and on top of that you get to enjoy an amazing view!
The dishes and drinks I've had all tasted good, although not extraordinary, and my friends and family were always very satisfied with their meals. The service was always courteous and I have never had a any sort of problem. I would highly recommend this restaurant to anyone who's never gotten to enjoy such a view!
