The bar, which opened in Amsterdam, is only open on weekends and has everything your hangover needs, from a comfy bed to an oxygen bar and even a masseuse.
The only thing you won't find though, is the hair of the dog, because the pop-up bar is alcohol-free, though it does serve vitamin-boosting smoothies and offers a fresh water fountain.
You'll be breathalysed by one of the 'hangover inspectors' to check you have been drinking, before gaining access to the innovative bar, which has been converted into a 'green oasis' with each bed boasting its own television.
Joep Verbunt, one of the brains behind the bar, said: "Most people share the opinion that the day after a night out is somewhat less successful.
"To overcome a hangover there are a few things you need: a good mattress, good food, fun and lots of vitamins.
"In the Hangover Bar all these elements are brought together for the first time."
Worse for wear revellers can indulge in a special food menu created by Foodora.
The bar is open from Friday to Sunday, between 10am and 6pm and we are afraid you'll have to bring your own Irn-Bru.
