    Fantastic wedding reception location in TriState area

    Our reception at the Diamond Jo was absolutely perfect, and I wouldn't change a thing (and I'm not just saying that because it was my wedding day). The room looked beautiful, the staff was amazing, and it went off without a hitch thanks to the work of the people there.

    From our first meeting with Olivia, the event coordinator there, all the way to the day after, we were taken care of. She was genuinely invested in running our event smoothly, getting us everything we wanted, and most importantly in our overall happiness. This was not another job for her; she truly cared about us. The venue itself was flexible, helpful, and very reasonably priced! They work with you to specify bar/food needs, scheduling; really anything you need. We offered guests a choice between pork or chicken, and I heard raving reviews on both. Truly do not have a bad thing to say; everyone in the Dubuque area needs to host an event here!

    Absolutely Amazing

    The Diamond Jo was absolutely amazing! It decided to not only rain but pour the morning of our wedding day. Our ceremony was outside at a different location. We called and they set up the ceremony inside and it was everything we could imagine! The venue was exactly was I had imagined. The staff were excellent. I would recommend the Diamond Jo to anyone getting married in the future!!
