Today over in Copenhagen, at the MAD4 symposium, Coi’s Daniel Patterson and Kogi’s Roy Choi announced the launch of loco’l, “a new kind of fast-food restaurant” that will serve “real food in a nice environment, and which could contribute to the neighborhood around it in myriad ways.” The famed Californian chefs will open the first brand of loco’l in San Francisco in the spring of 2015, and a Los Angeles outpost will follow. Details are sparse (“tasty, healthful, made from whole foods, good ingredients, principles of sustainability”), but Patterson and Choi confirm that they’ll open locations in both trendy neighborhoods and inner-city areas. And that Tartine’s Chad Robertson will develop whole-grain, long-fermented buns, which sure sound promising. [MADFEED]
