It is Comme des Garçon!
The many reasons why you should visit if you are in Singapore:It is in one of the oldest housing estates on our dot.
Personally, I do not know how to go there myself. [Update]It is certainly not in a corner but it is definately not considered in the central of our dot (to me, anyways.) Thanks, King (who ever you are. He must be a resident of the area.) Read his comments on the buses that goes there. Do not try the trains, please.

Details (please!)

If you are going there (which I had taken off from their website so that you will think that you had been to the right place). But most suburbs look like that (oh no.)
Postscript: Well, I read on the Her World about few months back that the stored had moved to Little India, that being one of my fav places to visit, looking out for it but in no vain! Boo. That was a false alarm! Thank goodness, New Paper had once published an article on this store and mention that it is still in Bukit Merah View.
