At the Hilton Harrisburg, Ad Lib is the traditional American Tavern, reinvented. Our weekend brunches, weekday lunches, happy hours, and dinners give you a chance to celebrate spontaneity, meet new people, and have a great time. Ad Lib is a place for everyone to share food and share stories, whether you're an overnight guest or a neighbor just dropping by. A strong emphasis is placed on locally produced food and beer. The service and decor, like the food, are comforting, simple, and unpretentious.
