Crafty students made a right meal of it at one of Gordon Ramsay's bottomless pizza restaurants taking advantage of the deal.
Matt Waters, 18, and his friends went to a branch of Gordon Ramsay 's which offers unlimited pizza for £16 per person with a selection of classic Margherita, pepperoni, charred aubergine and corn and chorizo.
The group, who study at Trinity Laban Conservatoire of Music and Dance in London, snuck lunchboxes into the eatery and filled them with enough slices to eat for a week.
They hid the containers in their handbags and tote bags and slyly put every second slice into the Tupperware.
Matt said the group managed to snag more than 25 pieces of extra pizza to take home from the branch in Camden, north London.
The teenager shared their mischievous gains in a video captioned "Gordon Ramsay bottomless pizza gonna [sic] feed us for a whole week."
He said: "We were using Tupperware to take pizza that was leftover on our plates from the bottomless pizza fest.
When the new pizza was placed on our plate, we ate half and packaged half.
"As broke students, we saw the bottomless deal and thought we may as well make the most of it.
"We had to be quite secretive because we didn't know what the staff would say, and none of them saw. We managed to take home about 25 slices between us."
The video garnered more than 50,000 likes and 450,000 views in a day on TikTok.
But some were left confused as to why they were trying to sneakily take the pizza, with people saying "you can just ask for takeaway bags?", "you know they have CCTV right" and "this ain't a flex".
However, most praised the group for their discreet finessing of the pizza and clever ways of packaging it away in their bags.
"This is genius," one person said, condoning the stunt.
"I didn't see a time limit on the all you can eat. You're still gonna eat it. Seems fair to me," another person commented.
A third joked: "I managed to get home with 8 margaritas 2x Hawaiian , 4x meat feast pizzas and fries in my underpants."
