So we here from our colleagues in San Francisco that there are chefs Twittering certain locations around the city where they will be cooking and serving once specific dish for a limited amount of time. Chez Roach Coach? Sort of…well Miami is blasting back with Latin Burger and Taco (http://latinburger.com/). Supposedly this is the gourmet equivalent of the San Francisco chef carts that are getting so much buzz. It’s worth a check out.
