£2,500 is where a restaurant build starts. At that level you get the menu architecture, a design drawn around your own room, the coded front end, Restaurant markup, and the crawl and redirect work a launch day needs.
Four things move it upwards, and each is itemised so you can drop any of them: a booking engine with card-held deposits, online ordering, a second site or a second venue with its own menu, and a photography day. A single-venue restaurant with one menu and a booking widget usually sits near the floor.
Put three questions to every quote you receive. Who can change a menu price after launch, which inbox does a booking actually reach, and does the number include the search work or does that arrive as a second invoice. Send us your brief on a call and we will answer all three for ours, or start with the pricing page.
