This venue is truly top notch. Stunning views, and cozy/classic look and feel to the interiors, and highly attentive staff. Bob was extremely responsive and Ann Marie, our Maitre D, was on top of it all the entire day and night of our wedding. All of our family and friends raved about the food as well as service. The historic dock and museum next door made for the perfect photo shoot we could have imagines and the view for our ceremony and into the evening with the back drop of the Great South Bay was absolutely stunning from day to night. I would highly recommend this venue to any LI bride looking for the beach vibe with a formal, classical backdrop.

I don’t know where to begin. Larkfield went above and beyond in every step of the way. They were so easy to work with and answered every question I had. Yes, it is worth every penny and it is true about the food! It’s a lot of food! Our guests are still talking about our wedding and how they had such a wonderful time and enjoyed every minute of it.

My husband and I were married at Royalton Mansion on May 30, 2026, and we truly could not have asked for a better experience. Our journey actually started with Rachel, the event manager at Royalton on the Greens. After attending her daughter’s wedding there in September 2025, she recommended that we tour the Mansion as well. From the very beginning, Rachel was incredibly helpful and knowledgeable. She connected us with several outstanding vendors, including one of the most important decisions of the entire wedding—our band. Thanks to her recommendation, we booked Faze 4 and chose the Scott Yanney band, and they were absolutely out of this world. They brought an unmatched energy to the night and helped make our reception unforgettable. Rachel also recommended After Hours DJ which kept the night going for our after party! At the Mansion, Arturo and his staff were exceptional. They were attentive, professional, and genuinely cared about making the day perfect. They didn’t just take care of the bride and groom—they made sure both sets of parents felt special and looked after throughout the entire evening. They were also incredibly accommodating with all of the details we dropped off during the week leading up to the wedding, ensuring everything was set up exactly as we envisioned. The food deserves special recognition. Both Royalton venues consistently deliver amazing cuisine, and our guests are still raving about it. One of the things we loved most was how customizable the reception menu was. We were able to hand-pick our favorites and ultimately chose the filet mignon, duck, and Chilean sea bass, all of which were phenomenal. The cocktail hour was equally impressive—multiple guests told us it was the best wedding sushi they had ever had. What truly sets Royalton apart is the people. From the first tour to the final moments of our wedding day, every member of the team made us feel supported, valued, and excited throughout the entire process. Whether you choose Royalton Mansion or Royalton on the Greens, you can expect exceptional service, outstanding food, beautiful venues, and a team that genuinely cares about creating an unforgettable experience. We are so grateful to everyone who played a role in making our wedding day so special.

Thank you to everyone who made our wedding a memory that will last forever, not just for us but for all our guests who attended. The venue was the talk of all our guests but not only that the staff who made this possible has are full sincere gratitude. The food was amazing and our families and friends could not stop talking about how great it was. All the coordination was top notch and shout out to Jazmin, Meghan, Anastasia, and of course Chef!

I cannot say enough to express how amazing our wedding day was at the Mariner estate. Yevgenia and Juan were both so helpful with the entire process. When we originally went to see the estate we had an entire tour of the place. We stayed for a while and we were told anything and everything can be moved around to our liking both inside and outside. There are so many ways to make this into the perfect canvas for your wedding or event… it’s also nice because the entire place is yours and you don’t have to worry about any other weddings happening. We even were lucky enough to be able to set up the night before since they did not have a party that day. We all got ready at the estate and it was nice because all the men got ready in one area and myself and the bridesmaids had two hidden suits in the back behind the stage to get ready in. Which allowed us to not run into one another before our first look. All tables and chairs were provided for us which was amazing and the list of vendors helped us tremendously. We used Felicos for catering and ended up getting Cinnabon catered for our “cake”. There was no problem as they have a full kitchen in the back. All of the guests absolutely raved about the beautiful space we had. They said the ceremony was stunning in the backyard and that they loved the amount of room we had in the estate! I would highly recommend the Mariner estate. Especially if you have a view of your own.

We just had a wonderful wedding at Westbury Manor and could not be more pleased with the experience. Their team is incredible, especially our bridal attendant, Claudia, and the maître d', Evelyn. This was a two bride wedding and Claudia was like our personal superhero! We both felt so cared for and pampered on our big day. Everyone at Westbury made sure that we were in the best hands, but we cannot thank Claudia and Evelyn enough. Our guests were entranced by the scenery and Pappi the peacock. This venue is absolutely beautiful in all seasons. One comment we've gotten a lot since the wedding is how impressed people were with dinner service. It was so seamless and everyone received their food at the same time (which is a challenge with a 100 person event). No guest went hungry. We also highly recommend booking Silverfox Photography for your Westbury wedding. Our photographer Amanda knew the venue inside and out, and her expertise meant we were able to get a lot of photos done before guest arrival and ultimately spend more time with our guests.

Our love for Seacliff Manor started before we ever said “yes” to the venue — it started the moment we walked through the door two years ago. From our very first meeting with Nick, we felt completely at home. His warmth and genuine care for us as a couple made the decision easy. We were literally calling to put down a deposit before we even pulled out of the parking lot. As our wedding day drew closer, Ian became our go-to throughout the planning process. As a bride with what felt like a million questions, I can’t tell you how much it meant to receive responses that were not only prompt but thorough and thoughtful every single time. He never made me feel like I was asking too much. At our final pre-wedding meeting, Ian created a detailed timeline mapping out every moment of our big day — and I mean every moment. On the day itself, he ran the entire event to the minute. His staff was incredible, the venue was absolutely stunning, and the food had every single guest raving. We had a jam-packed day with a lot of moving pieces, and Ian exceeded every expectation we had. If you’re a couple looking for a venue where you will feel genuinely cared for from the first tour to the last dance — look no further. Seacliff Manor is it.
