The Foodhallen markets itself as an indoor food market copy inspired by the likes of "Torvehallerne" in Copenhagen, "Mercado de San Miguel" in Madrid, and the "Borough Market" in London. Given their rather limited seating space, and the fact that it's overrun by tourists due to their Tripadvisor marketing (bribes paid?), you should avoid this place during their peak busy hours as it's likely you'll be sitting on the ground somewhere! The food is surprisingly great given how quickly it is prepared sometimes and on certain days it looks like they have children "locked up" behind the serving counters (Dutch hospitality is notorious for trying to pay as little minimum wage as possible, hence, the younger the employee, the less wage is required!). If you are looking for a place that is milieu- and environmentally-friendly, then you'll be disgusted to find out that most food is served on disposable throwaways and quality real cutlery is nonexistent. Many milieu-friendly places around Amsterdam now offer things like Join-the-Pipe in order to provide easier access to tap water for consumers in order to reduce (water) waste overall. Not at Foodhallen, where you are either forced to go the bathroom or wait in very long lines to score some free tap water or fill up your re-useable water bottle. If you are lucky enough to score a table and seating with your meal, the next challenge is finding a decently clean table surface (a lot of guests just rudely leave behind all their mess). Many times when we've managed to flag down a person wearing a FOODHALLEN t-shirt (I assume this means they are employed there?) to ask them to clean the greasy, crumby table surface, you can see them rolling their eyes (like what do you expect from me?) or sometimes blatantly saying "I'm sorry I don't have time for you" or "it's not my job". Now imagine you have to dine on the ground (tying it back to the beginning) how messy it must be. In short summary: Given this dirty, unfriendly environment, my suggestion is take your yummy food home since it's mostly served in take-away materials anyways and enjoy it in the clean comfort of your home.
