I finally made it to Jacqueline for a strawberry souffle.
I'm sorry, Hubert Keller's Grand Marnier souffle at Fleur de Lys wins, no contest. The texture of his souffle is lighter, less watery, more flavorful, and the outer edges crispy but less burnt. And I am a fool for creme anglaise, so he has an edge there. Plus, his souffle comes with complimentary a tier of petit fours.
I caught both restaurants late in the evening (10, 10:30), and both owners were working that night (Keller himself brought out our souffle, and Jacqueline answered the phone) so I think it's a fair comparison. I also ate at the bar at FDL, so I didn't have to have an entire meal there to enjoy dessert. The FDL version is about half the size and half the price of the one at Jaqueline.
Jacqueline has the edge in presentation.
