Our tour guide (I think his name was Thiys or similar) was the owner of the company and provided an excellent tour. He was very friendly, approachable and very knowledgeable, not only on food, but on many aspects of Amsterdam and the Netherlands in general. The pace was unrushed, with plenty of time to savour the food (and occasional drinks) and to have conversations within the group. Eight is the perfect size of group. The tour is expensive, but lasted over four hours and enabled us to sample quality local food. The freshly prepared herrings at the fish delicatessen were our highlight.
