Oysters and Pearls is Chef Thomas Keller's signature dish or at least that is the way it is portrayed. It is a very clever creation both in ingredients and name.
The dish has a novelty feel of familiar  but special ingredients and would be loved by most diners. The use of cassava is a very familiar and enjoyed ingredient and the use of it as pearls brings it out of the fun realm but still to be enjoyed and relished.
