Taking place on Saturday (29 August), the event will include food and beverage stalls and an ice cream festival complete with ice cream trucks, alcoholic pops and liquid nitrogen ice cream.
Attendees will be able feast on savoury foods from the likes of Liberty Cheesesteak Company and Melt Room, and beverage brands including Chambord and Finlandia Vodka will be serving up a range of adult-only concoctions.
The ice cream festival will feature Gordon Ramsay’s Union Street Café, La Gelateria, Yog Yoghurt and Whaam Banh Mi, among others.
While entry is free, those looking to attend will need to check-in on the Yelp app in order to be granted access to the celebrations.
The pop-up festival will be held at the Kids Adventure Playground in London’s Hackney from 12pm until late, and the company has partnered with Kids, a charity that supports children with disabilities, for the event.
Alex Shebar, London community manager at Yelp, said: "London has some great local businesses and this pop-up festival is being set up to celebrate them and encourage visitors to try something new. We encourage young-at-heart Londoners to come along and have some fun in the sun."
August has proved to be a busy month for Yelp - it also held its Epic Yelp Elite Photo Hunt Party at Event Prop Hire's showroom in London.
