I don't think I've gotten anything beyond some kind of ice cream with brownies and/or cookies and maybe some chocolate sauce and/or shaved chocolate and/or sprinkles. Either that or sorbet (we got sorbet at LeCellier and Akershus). Of course we've got other allergies so we're more limited. Actually, now that I think about it, they do have a berry parfait of some kind on the buffet at Biergarten and I think there may be something else there that's GF that we can't eat so I haven't made note of (we're always given Enjoy Life stuff because of our numerous allergies). The berry stuff is DELICIOUS over ice cream (the chef gets that for me when I ask since as I said, we're so limited in our options). Don't forget to get some Kaki Gori in Japan.
I've heard great things about the creme brule at LeCellier and I think there's a creme brule in France as well, maybe in the bakery? I saw a picture of an amazing dessert at Garden Grill but when we ate there several years ago all we got was brownies.
