Walking during the DAY is fine, anywhere in Grand Case.

As far as Orient Village restaurants are concerned, I think they very much compare with Grand Case restaurants now. And I personally really love the vibe of Orient Village. As I said, there are some parts of Grand Case that still have damage from Irma..

As far as walking from GCBC to restaurant row, it is a much shorter distance than Le Petit. I have to say that I PERSONALLY wouldn't do it, but I do not do much walking in general, due to physical issues. Again, I would check with GCBC to see if they provide transportation to restaurant row.
