what outside food and drink is permitted for lawn seats,

Go early and tailgate. Food is okay but beer is expensive inside.

Only 1 bottle of water

None. Except the one you buy inside there.

Bring outside food/water? Google how to properly tailgate and enjoy the summer and shows

I don't think you can bring in food or drink. Eat before you go.

You can only bring in 1 unopened water bottle. No other outside food/drink is allowed inside, though you can buy both from a wide variety of concession stands.

Everything very expensive inside. Don't think you can bring anything to eat or drink in. Go early and tailgate!

Get there as soon as the place opens up...you'll get a good parking spot to Tailgate in parking lot... best thing!! Maybe you can bring in water.

I'd look on their website i think you can bring things in
