For the past two years, Peter Cimino has been selling gourmet tacos in business parks in Amherst, N.Y., a suburb of Buffalo. In his bright lime green truck, creative entrées like chimichurri chicken and tomatillo pork sizzle. His Lloyd Taco Truck was personally invited by the owner of the Amherst Commerce Park to enliven the area and Pete was operating entirely on private property. But on Monday, Amherst shut his business down. A police officer even threatened to tow away Pete’s taco truck, for not having a permit.
