The rudest diner in the UK, where customers are promised the worst service imaginable, has arrived on tour in Leith, giving the capital the chance to see what the fuss is all about with this experience that's already taken down south by storm.
And, you just know that Edinburgh Live had to pop along to find out what Karen's Diner is really like, and why there are so many viral videos of this incredible experience, where the customer is definitely not always right – in fact, they are mostly, definitely wrong and will be told off for it too.
Having originally launched in Australia, customers at Karen's are encouraged to moan as much as possible throughout their dining experience only to receive short shrift from the staff.
