We came on the recommendation of tripadvisor and were amazed to be served one of the best meals (steak focused) in the Netherlands. Met by friendly and competent service we made a walk in reservation and were very pleased that the waiter already remembered our name 2hrs later and took my party of four to a prime outside table. On a Saturday night in down town AMS - we had a great location.
The food followed up to the same high standard, with amazing surf & turf (Lobster tail and filletsteak) or the substantial 400g Black Angus Steak... all four dishes cooked to order and delivered. The meat was top quality and certainly in my experience unrivaled in this city - I am out in AMS approx 8 nights a months.
There is a bar area inside that allows for pre or after dinner drinks, which makes BBQ Castell the perfect location for a great night out with friends.
