The event in Shoreditch from 20 to 22 July will be made up of vendors that use Just Eat for takeaway, including fried chicken and waffles restaurant Bird and Indian street food joint Indigo. There will also be live music and cocktails.
"Just Eat food fest: fantasy fusions" aims to take visitors to an "Insta-worthy world of playfulness", with slides, photo booths and ball pits. The experience is being delivered in-house.
Last year’s event welcomed more than 4,000 people, with 5,000 dishes sold.
