Marble, chandeliers, and a Great Neck name every Long Island family knows.
Leonard’s publishes square footage for its ballrooms, which nearly no Long Island catering hall does, and once you have square footage you can do arithmetic the salesperson would rather you skipped. Sixty-odd years at 555 Northern Boulevard in Great Neck, eight named rooms, and a Grand Ballroom that seats up to 850. Start with the numbers and the tour makes more sense.
Two marketplaces cannot agree on whether service fees are inside Leonard's packages or outside them, and that is the single most expensive ambiguity on this page. Wedding Spot's headline figure is also printed against 100 guests in the body and 50 in its own meta text. Leonard's site blocked everything except its FAQ, so nothing above has been checked against a rate card. Whether the per head quote is inclusive of service and admin is the question, and the answer belongs on the proposal rather than over the phone.
We read the venue's FAQ, and tried its homepage and wedding services page, which robots rules blocked, then Wedding Spot, The Knot, WeddingWire, Zola and Eventective. Checked September 2026. First party means the venue’s own site or rate card; marketplace means The Knot, WeddingWire, Zola, Wedding Spot or similar. Nothing here is averaged or estimated.
The venue's homepage and wedding services page could not be fetched, and Wedding Spot's page contradicts itself on the guest basis for its $14,740 figure.
All of this comes off Leonard’s own venue pages. The Grand Ballroom: “Seating from 300-850 Guests,” 7,640 sq ft, 112 feet 10 inches by 78 feet, note those dimensions multiply out to about 8,800, so ask on the tour which of the two is the usable floor. The Tiffany & Crystal Room: “Seats from 150 up to 250 Guests,” 4,790 sq ft. The Continental: 150 for a seated dinner or 135 buffet-style, 2,950 sq ft. The Empire Room: 100 seated, 70 buffet, 2,240 sq ft.
The Leonardo da Vinci Veranda is listed at up to 280 guests across roughly 6,000 square feet plus more than 2,000 square feet of indoor-outdoor space. It is sold as a room where ceremony, cocktail hour and reception all happen without moving. The Provincial Room is described as a cocktail room with direct access to the west patio. The Collonade Room is described as flexible, and the Holiday & Parisian Room rounds out the eight. None of the three publishes a capacity, so none belongs in your comparison until you have asked.
The same 7,640 square feet is published for anything from 300 to 850 guests. That is an enormous swing inside one room, and it is the single most useful thing on this page. Ask for a floor plan drawn at your own guest count, with the dance floor and the band on it. The same question applies to Westbury Manor’s Manor Room, which we walked through on the Jericho Turnpike page.
Nine square feet a person is a real, legal, functioning room, it is also a room with a full dance floor and 850 chairs in it. So go see it set for a number close to yours. Ask what the Grand Ballroom looks like at 800 and then ask what it looks like at 400, and watch which answer they are more comfortable giving.
Leonard’s own site publishes no prices, no minimums and no fees. Its headline capacity line is “from intimate gatherings of 50 to spectacular celebrations of 1,000+ guests.”
LongIslandCateringHalls.com, which is a directory and not the venue, lists a range of $70 to $175 per plate, claims the building can hold up to 3,000 guests, and says it runs three events concurrently. We are naming the source because we cannot verify a word of it, and the 3,000 figure sits badly against the venue’s own “1,000+.” Use the per-plate range as a rough shape and check it against our pricing research, not as a quotable number.
Which makes the honest tour question something other than how many rooms there are. Ask how many weddings are booked on your date, then ask which entrance, which lobby and which bathroom block are yours for the night. Get that in writing before the deposit clears, because it is the answer that determines whether the evening feels like a wedding or like a shift. If a shared building is a dealbreaker, our smaller-venue list is the better place to start.
