In a residential area near Erasmus University, In de Keuken van Floris restaurant feels like an enchanted forest with its autumnal tones, wooden surfaces and wall covered by thick, green Icelandic moss. Offering no predetermined menu, the chef-owner Floris Versluijs whips up what he pleases from an open kitchen island outfitted with a vertical wood-fired stove and jars of pickled and fermented substances: miso, kombucha and more. The nightly concoctions might include forest vegetables and flowers in a petri dish with a gel made from tea and mushrooms, or lamb neck cooked for hours over the wood fire and served with fava-bean kimchi. Saturday’s 10-course menu is €89, without drinks.
