Beach feeling in the middle of the city
In the heart of Düsseldorf’s historic section of town, the trained biotechnology engineer has fulfilled his dream of independence and opened his first shop – Rollacosta, the first Ice Rolls ice cream parlour in Düsseldorf. 'I've always had a passion for food and with ice rolls there are countless flavour varieties to try – I think that's what fascinates me about the whole thing,' says Demirtzis. 'It never gets boring.'
And indeed, a glance at the menu proves it – with variations such as raspberry-chocolate muesli, sesame honey or bubble wafer. The restaurant is reminiscent of a beach hut: with wooden materials for the counter and menu board, sand as wallpaper, a large area of painted sun and surfboards as decorative elements for the obligatory visitor selfie.
The ice cream base: A vegan recipe from a pastry chef
What makes his Ice Rolls so special? The base cream certainly plays a role. Demirtzis developed it together with pastry chef Marc Witzsche. On a vegan basis – all toppings and ingredients should develop their full flavour. The machines for the production of rolls were also developed by Demirtzis himself, and they fit perfectly for precise work. Sustainability and the avoidance of plastic also play a role:Rollacosta offers experience gastronomy in a cup. So I need a reliable partner at my side, like METRO.

Cups and spoons are made of cornstarch and are 100% recyclable. A concept that goes down well. On the opening day, people were queuing up in front of his ice cream parlour, sometimes without knowing what was in the shop at all – simply because the queue was so big that they were convinced it must be something good.
