Can you bring your own water into the venue? My friend is attending a concert here.

I don't think so

No, the only thing allowed are keys, wallet, and small purses. No back packs or anything bigger than a small purse or wallet.

Sealed bottle water only

No

I dont think so. I did take any drinks with me but i saw people dropping their waters on a big container

I don't think so, when I went I bought a bottle of water and coke but they removed the caps, so I guess they will not let you in with a bottle.
