Tonight's dinner 4/29/16 with friends was unfortunately the last we'll spend at Bella Fresco. Service was extraordinarily slow, even for salads. Meals took a while to be delivered. 2 friends had comp tickets from the restaurant's owner for 2 free meals based on the previous time's bad food. Tonight's on-duty manager refused to honor them even though the comps were signed by the owner and shown to him. The restaurant business in Charlotte is highly competitive and every customer is valuable - especially repeat customers. Tonight was the last straw and no amounts of comps will get us back. Arrivaderci.
