Atlantis Banquets & Events

What Atlantis Banquets & Events does

Atlantis Banquets & Events is a privately held, full-service event venue operating within the Long Island Aquarium complex at 431 East Main Street, Riverhead, NY. The venue combines a 5,310-square-foot formal ballroom (Sea Star Ballroom) overlooking the Peconic River, the 4,600-square-foot Coliseum Room embedded with tropical aquarium tanks, a 2,200-square-foot Riverfront Room, a 900-square-foot Italian-marble Foyer, and an outdoor Riverside Pavilion, collectively accommodating events of up to 650 guests. Its principal differentiator is the physical integration of aquarium exhibits — most notably the 120,000-gallon Lost City of Atlantis Shark Exhibit — into the event experience, supported by add-on animal encounters (shark dives, penguin and sea lion interactions, butterfly garden portraits) unavailable at conventional banquet facilities.

The company operates a single-revenue-stream business model anchored on venue rental plus mandatory on-site catering, with revenue generated per event rather than through subscriptions or licensing. Catering prices range from approximately $39.95 per guest for simpler luncheon offerings to $99.95+ per guest for traditional evening events, with full bar service (including top-shelf liquors) bundled in and Premium/Signature upgrades available. A $1,500 deposit secures the date, with a milestone payment schedule culminating 14 days before the event. Pricing is quote-based and varies by space, date, guest count, and menu.

Atlantis Banquets & Events serves three customer segments: wedding couples (primary), social celebrations (Bar/Bat Mitzvahs, Sweet 16s, Quinceañeras, proms, reunions), and corporate clients (holiday parties, fundraisers, conferences, trade shows). Distribution is sales-led through direct website inquiry, phone sales, on-site tours, wedding platform listings (The Knot, WeddingWire, LIWeddings.com), and periodic showcase events. The venue is embedded in a hospitality ecosystem that includes Hyatt Place Long Island/East End, The Preston House & Hotel, Treasure Cove Resort Marina, Seaside Grill, and Long Island Canoe Kayak Rentals, enabling multi-day destination-style events without travel. Headcount is 101–250 employees, and the company is privately held with no disclosed funding, parent entity, or public financial reporting.

Emerging players

• Georgia Aquarium: Atlanta-based aquarium that hosts private events, weddings, and corporate functions within its exhibit spaces. Most analogous operator to Atlantis in offering aquarium-themed event venues, providing a benchmark for monetizing aquarium assets through private events.

Direct peers

• Crest Hollow Country Club: Long Island (Woodbury, NY) banquet venue with multiple ballrooms and on-site catering serving weddings, Sweet 16s, and corporate events. Comparable in scale, customer segments, and mandatory in-house catering structure.
• The Mansion at Oyster Bay: Long Island (Woodbury, NY) banquet and event venue offering weddings, mitzvahs, and corporate events with on-site catering. Direct competitor in LI mid-market banquet venue space.
• The Water's Edge: Waterfront wedding and event venue in Centerport, NY on Long Island's North Shore. Directly competes for Long Island waterfront weddings and corporate events with similar capacity and full-service event production.
• Oheka Castle: Historic luxury mansion and event venue in Huntington, NY hosting weddings, galas, and corporate events. Competes with Atlantis for premium Long Island wedding bookings with on-site catering and luxury positioning.
• Danford's Hotel & Marina: Boutique hotel, marina, and event venue on Long Island's North Shore. Comparable to Atlantis's Hyatt Place and Treasure Cove Marina co-location model — bundles lodging, waterfront, and event space for wedding weekends.
• East Wind Caterers: Long Island banquet hall and caterer in Wading River, NY offering multiple ballrooms and on-site catering for weddings, Bar/Bat Mitzvahs, and corporate events. Closest direct competitor in event type, target market, and full-service in-house catering model.
• Sandcastle at Peconic Bay: Waterfront wedding and event venue located in Riverhead, NY on the Peconic River — same town and same waterfront as Atlantis. Directly competes for the same Long Island wedding couples, social, and corporate events with comparable capacity and on-site catering.

Regional players

• Gurney's Montauk Resort & Seawater Spa: Beachfront resort at the eastern tip of Long Island (Montauk, NY) hosting destination weddings and corporate events. Comparable ecosystem model — combines lodging, dining, and event space — but primarily serves a more upscale East End clientele geographically distinct from Atlantis's Riverhead base.
• Pier A Harbor House: Waterfront event venue in Battery Park, NYC hosting weddings, corporate events, and private celebrations. Comparable waterfront-plus-F&B event model, but operates in a different (NYC) geography from Atlantis.
