ABC News - The White Castle hamburger chain is sipping on the idea of selling alcoholic beverages at its restaurants. The 90-year-old company is testing beer and wine sales at a location in Lafayette, Ind., that combines a traditional White Castle burger joint with a Blaze Modern BBQ, a new restaurant concept also being tried out. In other cities, Columbus, Ohio-based White Castle is testing an Asian food concept and a restaurant that serves grilled sandwiches. Customers in Lafayette can buy a glass wine for $4.50 or a domestic beer for $3. White Castle spokesman Jamie Richardson tells The Columbus Dispatch (http://bit.ly/vWt7SS ) that feedback from consumers has been better than expected. But he says the company hasn’t decided whether to expand alcohol sales or the new concepts.
