It has a varied American menu and a bar crowd that can always be counted on for good conversation. The Men's Room is tucked in a corner at the top of a narrow staircase. There is no question that presidents and other VIPs have used the facility. It is said that JFK proposed to Jackie while dining at Billy's".
