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.

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.

Beyond Our Wildest Imaginations, Perfect Wedding!
We cannot say or write enough positive things about our decision to have our wedding at Union Mills Public House. It was, without an understatement, absolutely perfect. Our wedding was the best day of our lives, and Union Mills, their incredible staff, and the owners, Niko and Mary, were a massive part of making that happen. A Stunning & Unique Space: The venue itself is grand, spacious, and beautiful, yet it somehow maintains a warm, homely feeling. The design elements are entirely unique—from the grand chandeliers that gorgeously illuminate the main ballroom to the fantastic cocktail space. Plus, having direct access to the Carroll Creek River walk added a truly special and memorable experience for us and our guests. The Best Meal of Our Lives: The food is second to none. Honestly, it was quite possibly the best meal of our lives! The kitchen team absolutely knocked it out of the park, and our guests are still raving about the menu. A Masterclass in Management & Service: The staff were kind, friendly, attentive, and incredibly professional. Owners, Niko and Mary, have mastered a perfect division of labor that makes the entire planning process and day-of execution completely seamless: -Niko: handles the contractual and kitchen efforts flawlessly. -Mary: ensures the front-of-house efforts. Like the meal service, the bar, and the overall flow of the night. They were both extremely helpful, always willing to offer expert thoughts and recommendations while remaining completely open to new ideas. Everything at Union Mills is fully customizable and able to be molded into your perfect, unique vision. Final Thoughts: If you visit this place, you will be blown away. If you are lucky enough to host an event here, we promise you will be amazed beyond your wildest imaginations. Union Mills created as close to a perfect day as humanly possible, and they have our highest, most enthusiastic recommendation. Thank you to the entire team for making our dream wedding a reality! -Chris and Michele
