Online reservation site Bookatable said it had seen a 21 per cent jump in the number of bookings made for 10pm tables on Friday and Saturday nights in August 2016 compared to the previous year.
Bookings between 9pm-11.59pm have risen by 15 per cent, while Bookatable said it had seen a 13 per cent uplift overall on these days.
The Night Tube was introduced on 19 August and was hailed as a major boost for restaurants and bars.
Joe Steele, CEO of Bookatable, said: “Despite the delayed start, the Night Tube is proving to help bolster the economy, particularly the restaurant trade, by giving consumers more accessibility to explore the diverse restaurant scene London offers.
“An increase in bookings in August this year proves that there is an appetite for late night dining in the capital, and we’re excited by the Mayor’s plans to run more underground tube lines through the night and give more restaurants the opportunity to cater to this growing demand.”
Over 100,000 people used the Night Tube in its first 48 hours, and Transport for London expects the number to rise to 200,000 per weekend by the end of the year.
