I'm not sure how you can go wrong with a food truck festival, so automatically I love Kookt! There are all kinds of food trucks available including burgers, smoothies, milkshakes, soul food, pizza, frites, sweet treats, BBQ, some of your favorite restaurants and a few stalls you would recognize from De Foodhallen (http://www.yelp.com/biz/de-foodhallen-amsterdam). Of course there is beer and wine, and if you look around, you can find some cocktails too!
There's a lot of space to walk around and isn't as cramped as some of the other festivals. I love the industrial feel of the area and the different sections of trucks. It's a little bit of a maze, but it pretty much follows one flow, so you shouldn't get too turned around. To get to the end is quite a walk. The location was good being right off the ferry from Centraal or the Westerdoks. It is well-marked and has space for bikes. But if you are coming from the ferry, I would just leave your bike where you got on.
There is music along with some small and some large stages for you to enjoy. Only downside to the main (big) stage was it was all standing room. I think it would be more inviting with chairs, or high tops to stand around and eat on.
The festival works on a token system (like many of them do) and there were registers along the way--not just at the entrance. And there were machines to insert cash to get your tokens. That might help quicken things. But the registers also take pin cards.
It seemed that most items were between 2-3 tokens, and they do have half tokens as well. You can find a few items for 1-1.5 tokens and drinks are usually 2-3 tokens. These tokens are 2.50 each, but it's a festival and everything is overpriced.
And in case you aren't aware, most people in Amsterdam speak English, so you will be fine if you don't speak Dutch.
