The study showed that Brits eat out an average 1.5 times per week and spend up to £53 per meal.
Despite earning 30 per cent less than those in the over 55s category the research found that people between the ages of 18-24 eat out twice as much as their older counter-parts.
Over 35s were found to prefer quality over quantity with 57 per cent of them more willing to spend money on one good meal rather than three cheap ones, while 71 per cent of younger diners would prefer to eat three cheap meals rather than one expensive one.
Mike Xenakis, managing director at OpenTable, said: “It is no surprise to discover that Brits are spending a healthy amount of their income on dining out. With the diverse quality and variety of food in the UK, there is more culinary choice for diners than ever before.
“Whilst London continues to hold the reputation as the country’s culinary capital, we are seeing more and more award winning restaurants opening in the regions, giving a larger percentage of the population access to world class dining.”
