Whole spring chicken marinated with rosemary oil and Balsimic vinegar – a premium Italy vinegar made from white grape juice. According to the chef, chicken and balsamic vinegar is the perfect combination because the vinegar flavors suits the method in making sauces and is perfect as marinade for a chicken dish. This Chicken Rosmarino (RM58) was just one of the main dishes we sampled at the new Hotel Jen Penang, George Town, Penang.
