Wonderful venue! Beautiful ceiling art and ornate sculptures and carvings throughout. Great sound quality. One downside: upon entering the person at the door told me no glad photography and no recording the show but that I COULD take pictures.
I got a few photos right when the artist came onstage but I know not to be a fanatic about it..about an hour later I attempted another photo and was immediately "jumped" on by an usher. "NO Photos!!"
Why the 2 different statements? Are pictures allowed with no flash or not?
Other than this one small incident...I had a wonderful time!
