Watch out for this one, it looks like it'll be a ripper. A new café, Aro Coffee. When we were there they were still in the process of getting fully up and running. It's a great space, upstairs is a long bright corner room, big low slung windows (all of which I managed to miss in my pic) overlooking Ma May with a great view and a relaxing feel.
At the moment they have a cool logo and the aforementioned space, but no actual menu. We could get coffee, orange juice, water or beer from a waitress with a wicked sense of humour over the situation. Recommended for a drink and street watching, will keep you posted on what else becomes available as they get it together.
