Sai Yeung Choi Street : Mong Kok MTR Station at exit E2, then walk along

This is a screen cap from Centamap I marked.

You can get out at the Mong Kok MTR Station at exit E2, then walk along Sai Yeung Choi Street to Ginza Plaza (you'll see a shop called Citicall). I marked the path in orange. Take the escalator down. I went to 6 shops that sold either clothes or shoes or eyes, and some even sold dolls or dollparts! There are more shops, most of them were closed when I went! The only shops I went to are at the basement, I wasn't able to explore upstairs because I was pressed for time so I have no idea if there are more upstairs.

The purple spot marks where Dollheart should be. I also went to CTMA Center to look for SugarMag, but I failed to find it! I saw a shopkeeper who owned a doll though, and she gave me the directions for Ginza Plaza when I asked her if she sold doll's clothes. XD
