OpenTable vs ResDiary: which is right for your restaurant?
This is the classic UK shortlist, and the two systems answer different questions. OpenTable sells reach: a large diner marketplace that can put you in front of people who have never heard of you, paid for with a fee on every cover it sends. ResDiary sells control: no commission on bookings, a deep operations toolset, and a smaller discovery network in Dish Cult.

OpenTable
The big marketplace name, with genuine discovery reach. The model is a subscription plus a fee for every cover that arrives through OpenTable itself; bookings you take on your own site are not charged per cover. The UK site shows "Contact us for pricing" on both its Core and Pro plans, so there is no published pound figure.
ResDiary
Established, operations-led and group-friendly, built around table management, yield rules and floor flow. Genuinely commission-free on bookings and it publishes its UK prices, but they step up with booking volume (a venue over its limit is moved up a plan automatically), payments carry a surcharge, and several capabilities other systems bundle (SMS, pre-orders, events, vouchers) are paid add-ons.
So which should you choose?
The decision comes down to one question: how many of your bookings genuinely need to be found for you? If you are new, or you have mid-week covers to fill and no mailing list, OpenTable's network is a real asset and the per-cover fee is the price of it. If most of your bookings already come from regulars and your own website, you are paying a marketplace fee for demand you already had, and ResDiary's commission-free model will usually cost less. Watch ResDiary's add-ons, though — SMS, events, pre-orders and vouchers are each billed separately, and payments carry a surcharge.
Full disclosure: we make a third option
This comparison is published by NomNom, a UK restaurant booking system, so you should know we have a horse in this race. We have kept our own product out of the grid above because the question you asked was about OpenTable and ResDiary. For completeness: NomNom is £29.99 + VAT a month per venue, with no per-cover fee, no contract and a 14-day free trial. We do not run a diner marketplace.

Common questions
Is OpenTable or ResDiary cheaper for a UK restaurant?
OpenTable does not publish UK pricing, so there is no honest headline answer. The shapes differ: OpenTable is a subscription plus a fee on every cover booked through its marketplace, so the bill grows with how busy that channel gets. ResDiary publishes its UK prices — £109–£295 + VAT a month by booking volume, plus a £99 set-up fee — with no per-cover fee, but with paid add-ons and a 1.2% charge on deposits and payments.
Does ResDiary have a diner marketplace like OpenTable?
Yes, but a much smaller one. ResDiary runs Dish Cult, a consumer dining guide. OpenTable's network is far larger and is the main thing its per-cover fee buys.
Does OpenTable charge commission on bookings from my own website?
No. OpenTable charges cover fees for diners who find you through its own website, app or affiliate network. Bookings taken through your own site are not charged per cover.
