- I think Klang Plaza 2, quite new at the time, if you look carefully at the scene starting at 1:37: the half-hidden building behind the actor and behind a tree?
No, it cannot be Klang Plaza 2 because Klang Plaza 2 was not there yet at that time (I checked), it isn't shaped like that, it is much taller and looks much more massive from that distance.
Then this one must be one of two twin buildings in a row, the one formerly hosting
Royal Princess bakery on the corner, circled in yellow in the photos below. You see it well at 2:38, it really looks alike if you observe closely.
The building seen at the far right side background in the same frame must be the one now hosting
Mezzo Coffee, third photo below.
I'd say the scene starting at 2:50 is at the junction of Ratchadamnern Road and Jomsurang Road, just along from Klang Plaza II.
Resembling corner but it cannot be Alfie. If it was, the two twin buildings in the photos below should be there in the scene, instead of the market place. As just explained, the one in the yellow circle is seen at 2:38 in the video, while the one in the red circle is the same as the corner building in your photo.
Also, if you were right, what would be the long low building seen on the left side background, behind the market?
I wouldn't rely on traffic direction, it may have changed since.
