Brown's Hotel in London has a Truffle Martini that's about 5x the price of an average martini. I never did try it, but if I was handed one at a party I'm sure it would have made an interesting conversation piece. It had chocolate liqueur, Martini and a truffle that was soaked in vodka for over 48 hours.

To me that's not a bad start. But I would really be WOWed if they could put together a rare wine tasting during the party. Let everyone have a taste of something extremely rare from their cellar. Better yet, having the tasting, in the cellar itself.

On our table for the tasting menu we ordered at the Do Leoni Restaurant (Hotel Londra Palace) in Venice was our menu imprinted with a personalized greeting. This lovely touch might serve the dual purpose of "place card" for each of your special guests.

I've heard of parties where Harry Winston and/or Piaget will bring a selection of their jewels and watches to a party and let everyone wear them around for the duration of the party.

I've always thought a string quartet would make a nice touch to a cocktail party. But if you really put that in perspective, getting Itzhak Perlman to perform at your party would be a jaw-dropping experience.

Then again, a harpist is one of those instruments that people actually say, "wow, look it's a harp!" Although, maybe that's not the 'wow' experience you're talking about.
