First off sorry the information I give is a bit sketchy at best but hopefully someone can help me

Me and my friend are off to Amsterdam in a few weeks and his brother has recommended a pastry shop in the dam square area where you can get a sharing platter of pastries and a unlimited coffee refill for around €15 to €20

The problem is his brother was hungover and high when he found the place and can't remember the name

Does anybody have an idea about this place?
