Diamond Jim's is conveniently located on both S Hwy 51 and the Rock River. Whether you choose to come by street or by boat, you'll always have a place to hitch your ride and kick back. Diamond Jim's used to be part of Diamond Jim's and Isabella Queen's. Now, both halves of this building have been transformed into one large facility with one half dedicated to our stage and the other half dedicated to our VIP lounge. Whether you're coming to watch the shows or be pampered, Diamond Jim's in Beloit, WI, is the place to go!
