Yes they have concession stands and they will mostly likely bit run out of food there
You are not supposed to bring food. There are concessions. Be prepared though. I went one time to get some snacks from concessions. It was just my luck. The had cheese but were out of nachos and they also had hot dogs but were out of buns. There is a 50/50 chance you could be disappointed. A few times I have gone and they had everything you could imagine. But at the same time, there have been a few times, where they had much of nothing.
