hi there - we will be in amsterdam next month with our (2) young sons - ages 5 + 3. we are staying in the de pijp but plan to be out and about quite a bit exploring. we want to eat delicious food, but we also want places that are casual - nothing too fancy or formal. our boys are good eaters and are well behaved in restaurants, but they won't sit for extended periods of time. we live in san francisco so we love fresh, seasonal food - we are open to any suggestions. thanks in advance!
