So, you might be wondering if you can bring in your own snacks and drinks to the Super Pit. The answer is, it depends. You're allowed to bring in empty water bottles, which you can fill up at the arena's water fountains. But as for food, it's a no-go - you'll have to buy concessions from the vendors inside.

There is one exception, though: if you have a medical condition that requires you to bring in your own food, you're allowed to do so. Just be sure to check with the arena staff beforehand to make sure you're all set.
