Watermelon has transcended the picnic table. Chef Christophe David serves it up as a frothy cold soup perfumed with the star anise, micro basil, dots of vanilla and a swirl of Banyuls vinegar that mimics the amber and gold tendrils of the original Dale Chihuly glass sculptures hanging overhead. Sipping the soup, topped with a crusty crouton plank dotted with chopped lobster, is like crunching on melon in a spice plantation.
