There's been a big increase in the popularity of burgers, with new figures showing the value of sales rising by a quarter in the last five years.
Research by Mintel for BBC Radio 5 Live's Wake Up To Money podcast says sales are expected to hit £5.2bn this year, up from £4bn in 2014.
In all, 63% of consumers will visit a burger outlet this year.
Thanks to delivery apps, 40% more consumers are having burgers brought to their home compared with 2018.
Freelance food writer and blogger Ellen Manning told BBC 5 Live's Wake Up To Money:
"Burgers are a firm and old favourite, but they've been taken to the next level.
"The patties are no longer stereotypically mechanically covered meat slapped together with a lettuce leaf on top and some squeezy cheese."
