    The Onyx Grounds was the perfect venue for my parent’s 50th wedding anniversary celebration. From the moment we first reached out, the staff was responsive, accommodating and kind. They helped us plan the layout of the space to ensure it felt intimate despite hosting 70 guests. The venue itself was clean, beautiful and inviting - the perfect backdrop for the special day. On the day of the event, the Onyx Grounds team was there to help make sure the sound system was working seamlessly and that everything ran smoothly. My parents and their guests had a wonderful experience at The Onyx Grounds and would highly recommend it to anyone looking for a stunning, welcoming venue for their wedding or special event.

    The Onyx Grounds was an absolute pleasure to work with as a wedding vendor. Their communication throughout the planning process was great - they were responsive, transparent, and helpful in answering all of our questions. The venue itself has a beautiful and cozy atmosphere that provided the perfect backdrop for the wedding. The team at The Onyx Grounds are good people who clearly take pride in their work, and the food served at the event was delicious. We highly recommend this stunning venue to any couple planning their wedding.
