A recent jaunt in South Beach saw me not grinding it out with Donatella on a foothill of cocaine, but instead sitting with pals at a Fatburger on Washington Avenue, scarfing on a Kingburger with a side of Fat Fries. It’s a fine burger chain — even Kanye West thinks so. The rap artist’s food appendage KW Foods LLC has the rights to open 10 Fatburgers in the Chicago area, and Kanye is wasting no time. The California-based cow-killer will have its first Windy City locale in Orland Park, with another to open in the Beverly neighborhood this January. Now it’s Jay-Z’s turn to step up and bring some of them fat burgers to New York City. Goodburger after all, isn’t all that good.
