I found Chicken Spot on zabihah( Unilocal for halal food) when I looked for a halal food in Rotterdam. The place is near to the city center, and is easy to spot on. The food is great, the staffs are friendly, and the prices are decent. I got a giant meal(burger, fried chicken, wing, fries and Pepsi) for € 7.15. They also have a clean rest room. Halal sign is visible on the window.
