The opening of an ABBA-inspired restaurant was enough to bring all four members of the Swedish pop group together for the first time since the film premiere of Mamma Mia! in 2008. Now in their late ’60s to early ’70s, Benny Andersson, Anni-Frid Lyngstad, Agnetha Fältskog, and Björn Ulvaeus made an appearance at a new restaurant called Mamma Mia! The Party, though refused to sing or pose for photos together. The idea for the Stockholm restaurant came from Ulvaeus, and shares the same Greek-island setup as Mamma Mia! the musical and movie. Fittingly, the restaurant serves Mediterranean food.
