Are there any restaurant reservation systems that focus on private dining and large-party bookings?

Yes — there are reservation systems that either specialize in, or handle private dining and large-party bookings very well. The best-known options tend to fall into two buckets:

Systems with strong private dining / events support

• Tripleseat – One of the most popular platforms for private dining, catering, and large events. It’s built specifically for venue/event sales, lead management, proposals, and booking workflows.
• Perfect Venue – Focused on event and private dining management for restaurants and hospitality groups.
• EventTemple – More general venue/event software, but used by restaurants, hotels, and event spaces for private bookings and group sales.

Reservation platforms that support large parties well

• OpenTable – Strong for standard reservations and has tools for large parties, private events, and guest management, though it’s not as private-dining-centric as Tripleseat.
• Resy – Good for higher-end restaurants and can handle large-party workflows depending on setup.
• SevenRooms – Very strong guest CRM and booking platform, often used for restaurants that want to manage VIPs, experiences, and private events.

What to look for

If your main need is private dining and event sales, look for:

• Lead capture and inquiry forms
• Floorplans / room management
• Event proposals and contracts
• Deposits and payment collection
• Banquet event orders / BEOs
• CRM and follow-up automation
