There is another one on the right as you head away from the resort towards Sea Pines. It is next to a convenience store if I remember right. They had very good donuts, I remember. I'm not sure if they are still open or not, because I've had to skip them last couple of trips due to diabetes.
I have to say, I see a lot of people rave about Signe's. We went there once and I didn't like it that much. I know that is probably blasphemy, but we haven't been back. Maybe it is they just don't serve the same kind of baked goods we're used to (Krispy Kreme).
