Well the layout is very different from Orchard Road..
Instead of the huge shopping centres of Orchard Road you have two rows of boutiques running along the road, set back at a short distance from a narrow tramway. On the one hand the feeling is just much less manufactured than in Singapore - somehow more intimate and nice. Yet, I can't help but think of the Orchard Road population set into this tiny street. Yeowch.
And the biggest difference - KeY isn't here to let me know when what I'm picking out is just downright ugly. And to pick out nice clothes I wouldn't normally even look twice at.
