The Friday of a Water Mill wedding weekend is its own event: a seated dinner for the families or a welcome party for everyone who drove out. We put Water Mill hosts in touch with one caterer who does the night before well, and we say what it costs in 2026.
Rehearsal dinners in Water Mill: what's different here
Estates on Mecox Bay and the ocean in the most expensive ZIP code on the South Fork, the Parrish Art Museum on Montauk Highway for a party of 300, farm fields and the two working mills, and the Halsey House of 1683 for the history.
Water Mill gives the Friday two options: a seated dinner at a village house, where a finishing kitchen and a place to stage staff decide the headcount, or a tented welcome party on an estate lawn with room for a bar, a raw bar and the cars.
Parties here follow the Town of Southampton, as its code is summarised: 48 hours’ notice to the Fire Marshal above 50 guests, a tent permit from the Fire Prevention Office for anything over 200 square feet, no tents in the driveway, and the Town named on the liability policy with liquor cover if the bar is open. Water Mill is a hamlet of the Town of Southampton with 2,506 people at the 2020 Census and a median home price of $5,885,000 in 2024, the third most expensive ZIP code in the country; the Town’s housing plan counts more than 60% of its houses as seasonal.
Event and tent permits in Water Mill run through the Town of Southampton Fire Prevention Office in Hampton Bays (special events and tents); the caterer we put you in touch with has worked with them before, and this page says when a permit is likely to apply.

FAQ
Rehearsal dinners questions
How far in advance should I book a Hamptons caterer?
For a summer wedding, 9–12 months for the caterer and 18–24 months for a Saturday at a venue that hosts weddings; the average American engagement is 15 months, and the Hamptons calendar is shorter than that. For a corporate gala or conference, 6–12 months; a retreat, client dinner or holiday party, 4–6 months; 50–100 guests, 4–8 weeks. For a dinner party under twenty, two to three weeks, with 48–72 hours possible for a simple menu and three to four weeks in December or for a Friday. Off-season weddings (January to March) want six months rather than a year. A third of all catering orders nationally land in the fourth quarter, so a December party is a September booking.
Read the full answer →Plated, family-style, buffet or stations: which is right for a Hamptons event?
Plated is the most staff (one server per 10–12 guests, one chef per 40 covers) and the most control, at $70–150 a person nationally; buffet is the least staff (one server per 20–25, one chef per 50) at $40–90; stations run $35–65 at the budget end and $175–350+ for chef-driven live stations, and cost more in chefs than servers; family-style sits between plated and buffet and its national pricing is genuinely inconsistent across sources. In the Hamptons all four land inside the $150–400+ local range for a wedding. The private house decides more than the budget does: a plated dinner for 150 needs a finishing kitchen and a tent for it; a buffet needs the space for the line; stations need the power.
How does Sagaponack Catering Co. work?
You tell us about the event once: what it is, when, roughly how many, where in the Hamptons, and the style if you have a preference. We put you in touch with one caterer who does that kind of event at that size in that town, insured and cooking from a permitted kitchen, and they call you within one business day. From there it is their tasting, their proposal, their contract and their staff. It is free for hosts; participating caterers pay us a referral fee for the introduction. We are not a caterer and we do not sell your details; the one company we send you to is the only one that gets your number. We cover 9 South Fork towns and 6 kinds of events.
