OK, experts. What's the oldest cardroom/casino in the United States? Let's say the place doesn't have to have used the same name or been under the same ownership but it must be a venue where gaming has gone on continously. The oldest place in my area is the California Grand Cardroom in Pacheco, Calif. It's previous names have included the Pacheco Inn, Eagle Hotel and Woolford Hotel. Has has poker and chips since 1854. Anyone know of a place in the U.S. with a longer history?
