For those who may have not yet heard of a "supper club", let me introduce you to what could be perceived as an 'exclusive underground' society. Exclusive it seems due to the nature of the concept; it's a dinner party, but you don't actually know anyone; it's a restaurant, but in some one's actual home; and, it seems hard to make a booking, because everyone else is somehow 'in the know' and set events are notoriously booked out.
