The riverboat and accompanying complex now offer not just slots and tables but also hotel facilities, restaurants, and an RV park. The Casino Queen in Saint Louis has evolved to be much more than just a gambling operation. Signs and billboards advertise the casino for many miles around, just in case anyone in the neighborhood had missed its glowing presence on the downtown riverfront. Saint Louis is one of a few cities that allows riverboats like the Casino Queen to moor up on a semi-permanent basis and offering gambling to the locals. Driving into Saint Louis from the East, one can't help but notice the Casino Queen.
