L’Ami Jean - which has been written up extensively - look it up on HO if it fits your interest. Great rice pudding. L’Ami Jean felt great in 2010-2011-ish, but less impressive in 2014-ish for us (definitely was very touristy in 2014).
While not traditional, I would suggest Hémicycle and one of the Japanese/French options Pertinence, Montee or ES.
