How do you know so much, are you Taiwanese?The Guanmiao one is a gem. From what I understand it underwent some intense renovation just before it closed, which probably helped it hold up so well.
Dianji's a personal favourite though, such a great facade and the interior was truly something to behold when it was intact - such a shame some contractors (possibly at the behest of the owner) ripped out the stage and all the wooden seating a few years back.
Dianji was miscommunication, going on a news report. It was supposed to be a site survey, but the owner removed the seating and stage which was debris anyway, and would have to be replaced.
