Amazing Service, Amazing Team
I can't say enough how the process of working with the Union Mills team was seamless. Our first tour of the space we fell in loved with the venue. Beautiful and spacious are not enough words to describe it. Niko was incredibly knowledgeable about the wedding and venue industry, it made us comfortable to book. With all that it takes to plan a wedding, the Union mills team was always supportive and provided professional communication. When it came to the night before our wedding, we had an unexpected amount of guests that made us aware they could still attend. Niko and the team were so accommodating and helped us with the increase of guests. We were incredibly frantic, but this team truly helped us in a tight, uncomfortable situation. Wedding day was amazing and the additional stress was behind us. The staff was so friendly and honestly I've never had a wait staff make me and my spouse feel so special. They truly catered to us. We had a guest count of 153 guests and all their plated meals were fresh and hot. Drinks flowed seamlessly and the wedding was a success!

THIS is the venue you want to book!!!!
From our first conversation with Niko and Mary, we knew Union Mills Public House was the perfect fit for our wedding. They were quick to respond to every question and genuinely listened to what we wanted for our day, then made it happen exactly as we envisioned. The venue itself is stunning—the exposed brick walls and chandeliers create such a beautiful backdrop that the space really does most of the work for you. What impressed us most was watching the team flip the room from ceremony to reception in just 45 minutes, which felt like magic. Beyond their professionalism, Niko, Mary, and the entire staff were kind and warm throughout the whole process. We felt taken care of from start to finish, and we truly believe the investment in Union Mills was worth every penny.

Union Mills (venue and catering)
Union Mills Public House was the perfect fit for our wedding day. Niko and Mary were always quick to respond to any questions we had and provided a great deal of information up front which made booking an easy decision for us. We were impressed with how they worked with our budget without cutting corners on quality. The space itself is stunning, the food was delicious and served with exceptional presentation. Everything felt polished from start to finish. We felt taken care of the entire time, and our guests were very impressed with the venue all around. We'd absolutely recommend Union Mills Public House to any couple looking for a venue that delivers on both style and value.

Helpful staff, great owners, awesome bridal suite
Union Mills took excellent care of my husband (woohoo!) and I. Leading up to the wedding, we had multiple phone meetings, email interactions and text exchanges that allowed us to ensure the day went as smoothly as possible months leading up to the day itself. Mary was great at helping create the space, the waitstaff and bartenders were incredible, with lots of smiles on their faces throughout the whole night. They did not let us do anything without checking in on us or getting a drink in our hand! Niko designed a great menu and we really enjoyed getting to personalize our experience as much as we did. Also - the bridal suite is EVERYTHING.

Best Decision Ever!!
We wholeheartedly recommend booking Union Mills Public House! Niko, Mary, and their team were responsive and flexible throughout the entire planning process and worked with us every step of the way to make our vision come to life. We had a blast designing our menu with Niko and fully appreciate his passion and creativity. On the day of our wedding, the stunning venue and outdoor space provided the perfect backdrop, and the food was absolutely incredible. The staff treated our guests with genuine warmth and care, making everyone feel welcomed and valued. We would absolutely recommend having your wedding at Union Mills. The beauty of the venue speaks for itself, but the staff truly set them apart by going above and beyond to make our day special.
