I recently went on a trip with my friend to Singapore. It's truly a shopper's heaven! Nearly every train stop has a mall or department store attached to it, or at least one a few steps away. I think it's the most number of malls I've been to in a day.
I spent one whole afternoon at Orchard Road and I don't think I was able to cover the entire area. My favorite is Ngee Ann City because it has the bookstore Kinokuniya and this art store on the 4th floor, as well as Takashimaya Department Store. ION mall is also a great place.
What shopping places have you been to?
