I go here regularly, stocking up on beans, grains, and whole wheat pizza crusts and pasta. Fantastic bread counter in the back, where they make breads from all sorts of grains, such as millet.
There's always enough staff around to help with your questions, and the people at the checkout counter are so happy and cheerful (quite rare in the netherlands!). Prices are reasonable.Pros: aroma of fresh bread, reasonable prices, friendly staff
Cons: closed evenings
