Golden City is listed in this year's (Feb-2010/Feb-2011) phonebook, so it can't have been closed for too long. I find it a little interesting however, that Loopnet describes the place as "recently renovated" while work is clearly currently ongoing.
I'm not sure how long Golden City was there. Without going to the library, I can confirm that it existed in 1998, but not in 1976. Again according to Loopnet, the building was built in 1970, so there must have been other operations there over the years. And, speaking of the building -- it's rather an interesting one. The back part is fairly standard looking, but the trapezoid in front is quite unusual.
I wonder how accurate the English name is. If each Chinese glyph equates to a word (or idea) then there are four words getting squoze down into the two word "Golden City". Can anyone translate?
