Diners have used the "eat out to help out" scheme more than 10.5 million times in its first week alone.
Under the scheme, which is intended to boost the struggling hospitality sector, the government pays for 50% of a meal eaten at a cafe, restaurant or pub on a Monday, Tuesday or Wednesday.
The discount, which is due to run through August, is capped at £10.
The Treasury estimates the average claim at close to £5, making the cost of the policy around £50m so far. As of August 9th, it had received 10,540,394 claims under the scheme.
Chancellor Rishi Sunak described the figures as "amazing", adding those using the scheme were helping support the hospitality sector.
The government has set aside £500m to fund the policy. The scheme has led to an increase in the number of people visiting High Streets across the country, according to Springboard, which measures footfall figures. 83,068 restaurants have signed up to the scheme.
Government figures show that 80% of hospitality firms stopped trading in April and that 1.4 million workers were furloughed - the highest proportions of any sector.
"Britons are eating out to help out in big numbers," said Mr Sunak "And they aren't just getting a great deal - they're supporting the almost 2 million people employed in this sector," he said.
