White Castle, known for it's small, square, economical hamburger, is adding pork to its menu, at least as a test. The quick-service restaurant has reintroduced a pulled-pork sandwich in 39 Indianapolis-area locations.

The sandwich costs 99 cents and was first rolled out in the city this spring to test its appeal. The re-launch is being supported with promotions including giveaways, television and radio ad, as well as point-of-purchase materials.

"We've been testing the sandwich in the hopes of launching it system-wide," says Sandy Miller, regional assistant director of restaurant operations for White Castle System.

White Castle owns and operates more than 400 restaurants in 11 states.
