A partnership that begins a festival? Yes! For Restaurant Summum, it all started when owners Lars and Joella saw our Cocktail Parade in action at Lowlands. The speed, the energy, the quality… it made an impression.
Not long after, they reached out. Jorgos drove over with our demo bus, gave them the full Springbay experience, and from there, a new collaboration was born.
Summum is a unique gem in Zeewolde’s harbour. It’s a restaurant that combines high-quality culinary dining with a welcoming, accessible atmosphere. Lars, the chef, and Joella, the host, have built a place where everyone feels at home, but with dishes and drinks that meet the highest standards.
So when it came to cocktails, they wanted nothing less. The goal? To upgrade their bar to the same culinary level as their kitchen. That’s where Springbay came in.

Our collaboration doesn’t stop at hardware. Summum’s team is young, driven, and eager to master the craft of bartending. Through our Bartender Level program, we’ll support and motivate their staff to grow in skills, creativity, and efficiency. The Cocktail Station covers the high-demand classics, while Bartender Level helps take their cocktail menu and their bar crew to the next level.
For us, this partnership represents exactly what Springbay is about: helping venues align culinary excellence with cocktail innovation, giving entrepreneurs full control, and supporting their staff to grow.
