Its not a casino and its not in Nevada but I spent a long weekend in a hotel in Grantham (outside of Nottingham). Claimed to be the oldest hotel in England.

Angel And Royal Hotel Grantham
The Hotel Was Built In 1203 And Reputed To Be. Englands Oldest Inn Where 7 Kings Of England. Have Stayed Now Privately Owned. The Hotel. Has 30 Luxury Bedrooms And Will Offer Sevices. And Personal Thoughtful Extras That Will Make. The Hotel Regarded As The Best Town House To Stay In. The East Midlands.

Although I have always though "quaint" to be a euphamism for old...
