The great lakes adjacent state of Wisconsin has long been both an agrarian and industrial powerhouse. Major cities like Milwaukee and Madison stand in stark contrast to the rural agrarian plains. Wisconsin places strong emphasis on protecting its residents and its natural beauty using a fairly complex set of regulations. Thus, businesses often need a fair number of licenses and permits to operate.
In Wisconsin, taking your client or partners out for a business meal is a common occurrence. If the establishment is licensed properly then you are probably safe from getting them food poisoning.
