If you're in New York and willing to pay $2,300 for a hot dog, you should head over to the rooftop of 230 Fifth, where they'll be happy to charge you that. Granted, you must give them 48 hours notice, but they'll be happy to prepare the ludicrously priced meal for you. The upside is that the money is strictly for charity; it's being donated to City Harvest.
Since it's National Hot Dog Day, the best way to celebrate is by spending two grand on a hot dog. It is for charity, though.
