I am planning to attend the world cup final screening tomorrow. Is it possible to bring food and drinks or do I have to buy everything inside the stadium?

I've attended 4 screenings with my 4 yr old grandson. I pack his lunch insulationed bag, milk, veggies, snack and carry my own drink. No problems. Just don't bring large cooler, enjoy

You can bring a bottle of water. I have also seen some people bring in Starbucks. But they usually don't let food in. They have really good food trucks there serving first thing in the morning.
