What happens if a chef steps out from the kitchen in front of hungry guests? Constant feedback, compliments. That's what happened with Wesley Smulders after 10 years of hard work in the kitchen, taking of the blinkers and meeting people, this is street-food with professionalism.
With his friends they make dutch beef stew with special seasoning. I wouldn't think of this as a typical festival or street food, but in bread with the salad and roasted onions happened to be a perfect dish.
