You are all right to some extent! Today while taking the train to and from Maha Chai at the station opposite the end of Charoen Rat, I checked out the cinema situation.
There are three cinemas in the immediate vicinity.
1. is the "Sextile", open, active and opposite Robinsons almost directly. Name not known. Bht50.
2. is 200 meters into Charoen Rat on the the right. It appeared very closed today. Possibly named Hawaii.(see photo below)
3. is on Taksin soi 3(shown at the bottom of the map above) about 50 meters into the soi. It is being gutted right now but the shell is being left intact.
Google map of the area:
Gutted cinema on soi 3...note the line on the wall showing the stepped floorline of the cinema:
This is the closed cinema on Charoen Rat...possibly the Hawaii as described by Richsilver:
Limited to three pictures in a post, so can't show here the shots of "The extile Plaza", but it's easy to find...opposite Robinsons and open for business...easy to find..see Google above.
