Serendipity3 is doing it again: just a few months after debuting the most expensive fries in the world (a $200 order!), the iconic eatery is paying tribute to the now-discontinued cult favorite Choco Taco by offerings patrons its own version of the food. The entire concoction will then be dipped in what a press release deems to be “rare” ruby chocolate and, finally, topped with 23K edible gold.
