We went to eat at Arq twice during our visit, both times the food was incredible. The must-have is the dutch weedburger, the burger itself is delicious and the vegetable fries we took as a side dish were tasty. Besides that dish we had the wrap and the warm quinoa dish, both great as well. The only downside is that its' a bit on the expensive side.
Cons: Expensive, Vegan dishes weren't marked on menu
