Make a big deal out of it :p And find someone willing to pay for the publicity and exclusivity of having it served at their dinner or party.
I personally believe it's kindof easy to make money at it, because you appeal to a completely different customer group then what you ordinarily do. The people willing to pay 10000 USD for a night with a model, 5000 USD for a beautiful chefs knife or spend 25000 USD on champagne in a single night. Now when you throw a party or dinner where you have something exclusive enough to attract that kind of big spenders in the first place then the rest is not that hard.
