Atlantis was really fantastic, they accomodated me on everything and made the entire process of wedding planning enjoyable for me and my wife. The staff was fantastic both in planning and the day of. I couldn't have been happier with them or any of the vendors they recommended. They were easy and quick to communicate with, the food was excellent, the venue was gorgeous and everyone had a great time. I have family members and friends who hate weddings who stayed till the end and then raved about how unique, different and most important fun and memorable!
Our wedding was a dream come true thanks to Atlantis Banquets and Events. Both Steven and I were treated with respect and loyalty and also had top quality service. My family members were so impressed with the unique elegance that Atlantis provided for us. If you are a bride and groom-to-be and are not sure who should host your wedding, choose Atlantis. The recommended vendors such as ADA Photography and Sound Choice Entertainment were absolutely fabulous!
Everything about Atlantis was AMAZING! The staff was truly professional and made everything seem personable. They were always there when we need them and they answered all of our questions right away. The amount you get for the price was fabulous! My husband and I couldn't have been happier! All of our guests loved the venue. They loved the feel of the aquarium and just the way it was setup blew them away. We really couldn't have picked a better place to have our wedding!
If you want a unique and amazing venue for your wedding reception look no further than Atlantis Banquets & Events. This venue offers an event that every bride and groom dream of for their wedding day. Our wedding reception far exceeded our expectations from the moment that we were greeted with champagne and strawberries, experienced a unique cocktail hour in the aquarium amongst the sea exhibits, and then went on to enjoy the reception in the beautiful upstairs room overlooking the Peconic River. The service provided by the staff was exceptional beginning with the initial planning with Craig Alexander, to the actual wedding day with Lori, Jayme and Jacquie and all of the other staff who were very attentive to our every needs. The food served throughout the event was delicious and seemed endless. At the end of the evening our out of town guests had the convenience of staying next door overnight at the Hyatt Place East End. Many of our guests commented on how this was the best wedding reception they ever attended. Thank you Atlantis Banquets & Events for making our wedding day a memorable celebration!
