Well it does say in the tin: QBig is a big shopping arcade in BSD, Tangerang. I visited for the first time last week, when I bought some home appliances for my house at Courts electronic store, which is located at the same complex.
Not all stores are opened, yet this would be one of go-to destination around the complex. They even provide buggy service to go around! Interesting to see how popular this place when all stores are opened.
