Here's another Qdoba gone. I know the chain has also lost two stores on the Grand Strand in the last few years, so I have to wonder how well they are doing overall. I have to admit that I have not been impressed the three or four times I have stopped at a Qdoba. In particular, the burritos tend to fall apart quite easily and spectacularly, something that almost never happens at my favorite chain in this category, Moe's. (Barberitos is pretty good too, though we have none locally). On the other hand, commenter mamarose who reported this closing says that the Five Points store is doing quite well.
As of 21 August 2012, the electronic billboard near the Rosewood / Garners Ferry intersection was still advertising for the Woodhill location.
