We were at Cheval D’Or this spring. The food was so good we went back again with visiting family, specifically for perhaps the best “Peking” duck I’ve ever had (certainly the skin), and the soup with a foie gras-filled dumpling. It’s on our must-return list for next year.
I do agree with Carm that I wouldn’t describe the place as “‘fun” in any way, however. Not somber or unpleasant, to be sure, but definitely not “fun”. And not sure it’d be a good place to go with a large group, though that might be a mistaken impression.
