About Us

When it comes to catering halls on Long Island, there are an endless amount of options, but the challenge is not only in finding a location, but also in choosing the one that best suits your event. Whether you're looking for an intimate place for a quiet reception, a large hall for hundreds of well-wishers, or a unique setting surrounded by water, Atlantis Banquets & Events is the right choice. 

 A setting as special as your wedding.

Atlantis Banquets & Events creates a magical atmosphere for any social event. A once-in-a-lifetime celebration deserves a one-of-a-kind setting. From our waterfront location on the Peconic River to their spectacular aquatic displays, Atlantis Banquets & Events offers the ultimate wedding on the water.

But our distinctive atmosphere is only one of the advantages we bring to your celebration. We also offer incomparable service and exquisite cuisine, and can tailor a menu to your requirements and budget.

A unique backdrop you and your guests will remember forever—from impressive weddings, Bar/Bat Mitzvahs, proms, reunions, christenings, engagement parties, and children’s birthdays to holiday galas, corporate parties, team building events, fundraisers, and conferences.

Functions involving 20 to 650 guests, in settings as diverse as waterfront Riverside Pavilion, popular for cocktail parties, elegant Coliseum Room, perfect for formal evening receptions, breathtaking Sea Star Ballroom, our Terrace Room, perfect for bridal showers or post-nuptial brunches, and Peconic Meeting Room, conveniently located in the adjacent Hyatt Place East End & Resort Marina.

Atlantis Banquets & Events is located within the Long Island Aquarium & Exhibition Center and adjacent to the waterfront Hyatt Place East End & Resort Marina at 431 East Main Street, Riverhead, NY. For additional information, or to find out how to book an event, call 631.574.8008, or e-mail
