Booked Two Days Ahead. Or Two Hours.
How far in advance Belgians reserve, and how that shifts with the group, the day and the season.
HappyChef Datahub
Belgians do not plan their restaurant visits far ahead. The typical reservation is made just two days before the visit, almost one in four is for the same day, and only one in ten is made more than a month ahead. Big groups are the exception: they plan weeks in advance. These eight insights show how much notice a restaurant really gets.

How We Built This Article
Period
Reservations made from 1 October 2025 for visits up to 30 September 2026
Datapoints
8 insights, each resting on at least 37,373 datapoints (the largest on 37,409), from 38–42 Belgian restaurants.
Method
Anonymous aggregates over Belgian HappyChef restaurants, each restaurant weighted equally, with every figure over at least five restaurants and 1,000 datapoints.
About This Data
This analysis is based on Belgian restaurants that use HappyChef: 38–42 restaurants, depending on the insight. Restaurants that joined during the period are normalised so the growing number of restaurants never inflates a trend, demo and test accounts are left out, and placeholder values (an empty field saved as zero) are ignored.
Every figure is an anonymous aggregate. Each one combines at least five restaurants and at least 1,000 datapoints, no restaurant is named or singled out, and no name, email address, phone number or remark of a guest is ever published.
