This is in one end of the Hyatt Plaza Shopping Mall, at the Villaggio Mall end. You need to go into the furniture shop and up the escalators in the entrance there, then turn right at the top and Diaso is right in front of you.
The shop is just full of stuff! If you want a cheap mug for work, some stationery, a shower cap, etc etc, this is the place to go. It is fun to walk around and see all of the fascinating things they have on sale.
If you are in need of some sort of small object then it is worth popping in to see what they have. I got some good spectacle/glasses cases there.
You need to go and look to see if they have what you want :-)
