Grocery stores/local Market in DB?

[Elifabelle]

Hello,
We'll be moving to HK in about 2 months with a 7 months old baby. Thinking about DB or Tung Chung.
- How many grocery stores are in DB?
- How long does it take to go there from the furthest point?
- Is there a wet market in DB?

I know there is a wet market in Tung Chung
- How long would it take to go there from DB?

Thank you
