It's all in the name. Pfanntastic is fantastic!
Having eaten Pannenkoek in Amsterdam for a week straight I can say Pfanntastic is the real thing. If you know what you're getting into you'll love it. If you're unfamiliar with dutch style pancakes then you're in for a treat (I suggest sweet & savory).
The atmosphere is that of a family run establishment with consistent staff, toys for the kids and a friendly no nonsense approach to your visit (no 2 people in the 6 person booth on the weekend).
A new approach I've taken to dining at Pfanntastic is to have pannenkoek for the meal and a sweet pannenkoek as desert. It's the only way to go!
