Do they serve alcohol?

I definitely had some wine at the opera.

I want to say, depends on the event. I have not seen it for school or events by kids

Yes, alcohol is served at intermission in the concessions

For Taj Mahal/Keb Mo concert, "Taj Mo", they served Budweiser and Yuengling, beer, white wine. I was happy you could take a beverage to your seat. The acoustics in that room was great!
