May I bring in a cardboard box of Cabernet and plastic wine glasses for the symphony tonight ?

Outside beverages except water in an unopened bottle. It is that way for concerts. They want to be able to get the alcohol sales. But you can always call the venue and ask

Yes. But no glass in the seating area.

I guess if your bold enough... Conceal it ,then put it in a large purse😉

I think so, not entirely sure. They were definitely letting us bring in Fair food during the fair.
