Hidden Gem

The venue is up the road from my parent’s house and I grew up going to various parties here and they’ve always been amazing. I also had my bridal shower here. They really are a hidden gem. The view is incredible and it has such a romantic charm to it. We had the most amazing sunset and everyone kept raving about how beautiful it was. Bob was so easy to work with throughout the process. The night of I had Annmarie as my maitre’d and she was amazing. She ran the show, kept everything in check, and bustled my dress in 3 minutes and it never broke. Camille was our bridal assistant and she is so so sweet. The food was delish, the staff was on top of their game. The bartenders were great too! I was also very particular on how I wanted things set up and was able to go the day before and decorate exactly the way I wanted it to look! It put me at such ease to know that everything was already done with my exact vision. It was truly all perfect

Perfect Place for the First Night of the Rest of your Lives Together

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.

amazing wedding venue! 10/10 recommend

Our wedding at the Mansion at West Sayville was everything we ever dreamed it would be. The venue itself is so beautiful, and is spacious yet intimate. We had 101 guests and it was the perfect size for everyone to party comfortably. Working with the team at the venue was a breeze: Bob was easy to get in touch with and always answered all of our emails in a very timely manner; Ann Marie ran the day of spectacularly and made sure everything went smoothly; Camille the bridal attendant was so sweet and attentive and always made sure we had food and drinks in hand; all of the wait staff and bartenders were top notch and our guests had nothing but wonderful things to say about our wedding. Definitely recommend everyone to have their wedding here, you will be so happy!

Wedding Review

I cannot say enough great things about this venue! Our wedding day was perfect and it has so much to do with this venue and everything it entails. Bob was wonderful to work with and everything was exactly how we wanted it. The food was amazing and we couldn’t be happier with how everything turned out. Our maitre’d AnnMarie was truly amazing and helped our day go so smoothly! I would highly recommend having your wedding here!!!

The Best Venue & Staff Ever!

The most perfect venue! If you’re looking for an intimate location in a beautiful setting this is the spot. We do not have enough amazing things to say about Bob, Ann Marie and Camille. They were amazing to work with from the moment we toured the venue and could not be happier with our choice. All our guests said it was the most amazing they’ve ever been too and that the food was incredible. We’re so happy with our decision and could not have asked for a better team on the most important day of our lives. Thank you again!!

Incredible

My husband and I just got married this weekend and cannot express our gratitude enough to the Mansion at West Sayville crew for making our wedding absolutely perfect. Steve, Ann Marie, JoJo and Hannah made our wedding even better than we could've imagined , during a pandemic no less. Steve has been so easy to work with since booking 14 months ago and has been incredibly accommodating and available for all our questions/concerns in light of all the recent, ever changing regulations throughout this year. We converted to a microwedding with zero issues nor pressure with 7 wks to go to our wedding and truly could not have dreamt up a better wedding day. We have nothing but the best things to say and would do it over again in a heartbeat!

Amazing all around!!

Wow I cannot say enough wonderful things about West Sayville! Steve was such a huge help throughout my planning process and quickly responded to any questions I emailed him. In the few days before our wedding, I met Ann Marie and she was so incredibly sweet, knowledgeable and on top of things. During our wedding, Ann Marie kept everything going smoothly throughout the night and was really helpful with my bustle and fixing my hair after it got a little messed up when pulling my veil out. She is a miracle worker. Everyone has been raving about the food, there was not one complaint! All of the staff was so sweet and responsive to any requests we had. The grounds are so gorgeous. Unfortunately the sun set before our cocktail hour began but what can you do! We did the package that was offered and all included vendors were fabulous. I most definitely recommend this venue - you cannot go wrong!!
