I lost my glasses at this theater. I tried calling, but I got an answering machine that wasn't helpful. How do I contact this theater to see if they found my glasses?

Try hitting either ext. 399 or 0 when the auto reply comes on. If not your best bet is just to go there. They usually have a large amount of things in lost and found.

Look up their number on Google

I don't know a phone number but maybe there is contact via email on their website

If you can, try and go there. And call just as your goin in.
