You can get fast food there but there's a few nice places in Antrim to eat too! Nandos, the Boathouse, the Stone Hound.. there's also McDonalds etc!
Its hard to find somewhere to sit and its mostly street food, it can be hard to eat it so depending on the age of your kids I would eat a big late lunch or early dinner elsewhere, they at the market just get hot chocolate or a crepe instead of trying to feed everyone from different food stand queues
Thank you all!
There are food trucks there, but the lines can be quite long depending on time etc. food is reasonably priced and nice!
