Billy Big Balls on West Street has a giant ball pit similar to those seen in children’s play centres, where revellers on nights out can chill out or take a selfie or two.
The rules state that up to 20 people at a time can enter the ball pit but they must not be drunk and must not throw the balls.
The bar also offers beer pong, plus two for one cocktail deals on Fridays and Saturdays.
It has opened in the former Players Bar, which was a staple on nights out in Sheffield city centre for 14 years.
We send a photographer out to get some pictures to give you a sneak peak inside.
