Review for Diamond Jo Casino Dubuque Review For Diamond Jo Casino Dubuque Google User Mar 18 '16 at 16:09 Good venue. Not a bad seat in the house.

The only negative was during one show (Jewel) a while back, the noise at the bar got loud. For those that wanted to listen, it could be frustrating. Jewel actually had to stop and quiet everyone down. View full site to comment or like
