If you thought five days is a bummer, what about minimum two weeks in advance order for the world’s priciest hot dog? Its name implicates the Japanese flavors added. This is a foot-long smoked cheese bratwurst on a brioche bun with slices of wagyu beef, teriyaki-grilled onions, maitake mushrooms, foie gras, shaved black truffles, caviar, and mayonnaise. Japanese mayonnaise, of course.
