The arrival of gourmet food trucks to Miami made hungry stalkers out of even brown-baggers. Some of them sit by their computers, refreshing Twitter feeds and Facebook pages, waiting for the message that tells them where the truck will pop up. An internal debate follows: Should I go? Do I have time to go there and get back to work? Admit it. You've done it. Food on wheels isn't new, but these trucks sell food such as pork belly burgers and make finding their location part of the dining experience. It all began last December when chef Jeremiah Bullfrog's GastroPod Miami, Ingrid Hoffman's Latin Burger & Taco, and Flavio Alarcon's Yellow Submarine appeared in our dining consciousness. The trucks quickly gained followers and fans. Famous chefs such as Michael Schwartz and later Jonathan Eismann then followed with vending carts. They appeared at the art walk in the Design District. A Miami street food fest is said to be in the works. So what's next? A truffle truck? A foie gras cart? Who knows? But these mobile eats are likely to be around for some time.
