The culinary experience is what you're paying for! And what an experience it was! I took my girlfriend here for her birthday and we both loved every minute of it. The novelty of the entire experience and the appreciation of our own senses after it has culminated is a thing of surreal existentialism.
The food is mediocre, but like hundreds have said here... that ain't what you're paying for. You're paying for eating in the dark when you can't even see your own hand in front of you. You're eating in the dark where the only way you can make sure your sweetheart is still there is to hold her hand or play footsie! The romance of it all is quite ecstatic.
Go and experience it! :)
