I balked when I first saw that Rick Bayless was serving $12 sandwiches at his “street food†spot Xoco. Sure, they were cheaper than a Frontera Grill entrée, and the smoky pork was enveloped by the best bread I’d tasted in the city. But you can score a torta for half the price at many local taquerÃas, including my favorite: the Cemita milanesa at Cemitas Puebla in Humboldt Park. Is Xoco worth the extra six bucks? You be the judge. (This article first appeared in Chicago magazine in a different form)
