Step thru the doors of the Ruby House restaurant in Keystone and we will take you back to the days of the Old West in our elegant turn-of-the-century dining room. Red velvet draperies and wall hangings blend with period pictures and prints beautifully displayed in antique frames. We have antique handguns and rifles as well as carnival glass and china so there is something of interest for everyone. The Ruby House is located on the Keystone strip, two miles from Mount Rushmore National Memorial. We are open from April through October and offer a full lunch and dinner menu 7 days a week. Our season hours are 11 a.m.-4 p.m. and 4-9 p.m., Sunday through Saturday.
