Joined by his DJ friends Martin Garrix and Dillon Francis, the Bad Neighbours star made the most of his stay in the Dutch capital and appeared to have a great time celebrating the milestone occasion.
On his actual birthday, he shared an Instagram picture of himself and his buddies riding their bicycles throughout the Amsterdam streets, captioned 'rollin with the homies! Thanks to @DilllonFrancis and @martingarrix for the coolest birthday ever'.
A few days before, Zac also hit up award-winning restaurant Noma in Copenhagen with rumoured girlfriend Sami Miro. Run by renowned chef Rene Redzepi, Noma was named best restaurant in the world no less than four times - and lucky Zac even got to snap a picture with Rene after taking a tour of his 'test kitchen'.
That wasn't the only fine dining Zac enjoyed during his birthday week, however - his friend Martin also shared a hilarious picture of the their "romantic dinner", which was a table full of foil-wrapped food packages!
All in all, it looks like Zac's 27th birthday celebrations went off without a hitch - we wonder where he'll be jetting off to for his next birthday?
