RATIONAL has been an integral part of Chef Keller's culinary journey since the 90s when he first experienced its innovative combi oven. From that moment on, RATIONAL has held a prominent position in his kitchens, continually shaping and enhancing his cooking techniques.

Chef Keller acknowledges the transformative power of the RATIONAL SelfCookingCenter®, stating, "The RATIONAL SelfCookingCenter® has empowered us to embrace culinary dynamism and create a menu that constantly evolves."

RATIONAL ovens play a vital role in Chef Keller's restaurants and bakeries. They are utilized throughout the day in the preparation and pastry kitchens, while the chefs rely on them for on-the-spot culinary preparations. Even after the complete renovation of the French Laundry kitchen, RATIONAL continues to serve as an indispensable cornerstone. Chef Keller proudly asserts, "RATIONAL is an essential part of our culinary team on the line."
