It’s really easy to make the ‘most expensive’ of anything. Either take a regular item and cover it in diamonds, eg those million dollar bars from Victoria’s Secret. It’s just a bra with a million dollars worth of diamonds.
The same rule applies to ‘most expensive food’, just add truffles. Truffle oil, truffle butter, or just chuncks of truffles. Seredipity made a $69 hot dog. It’s a 12 inch, all beef hot dog covered Foie gras and cooked in truffle oils and butters. Yum. The video from 2010 just had a small viral surge on social networking and blogging sites.
