Resembling a 3D art installation, this conceptual offering from the famed Adrià brothers is a 40-course tour de force of cutting-edge gastronomy across six dining spaces. A meal takes 3½ hours and includes customised cocktail pairings (you can order additional drinks). There's a minimum of two diners; reserve months in advance. A €100 deposit per guest is required upon booking.
Once your booking's confirmed, you'll receive the door code by email. Note that it's not suitable for kids, vegetarians or anyone with dietary restrictions. Diners are instructed not to post images on social media to preserve the enigmatic experience.
