They have some gluten- free items, but be sure to expressly state gluten- free even if the item is marked as gluten- free, so that they take care in the preparation, which they will indeed.

They can get very busy in summer on good weather days.
It's a welcoming environment with great views, great pizza, and a warm welcome.
