Tonne 15 serves German dishes with a focus on hearty options like currywurst and fish sourced from local Maasholmer fishermen. The casual, maritime-themed restaurant has a friendly staff and is appreciated for generous portions and good value—vegan visitors often highlight the labeled vegan currywurst served with vegan mayo. While meat and seafood are central here, vegan choices are clearly indicated and worth trying. Outdoor seating and wheelchair accessibility enhance the dining experience.
