The app suggests there is a shop of some kind but there is no shop or supermarket here
Three cafes in town, the first one you come across is good, lots on offer including vegetarian meals, lots of cold drinks and snacks. Didn’t check out the second one, the third one as you are leaving town is not great, very small selection and rude staff!
I’d stick to the first cafe! The lady who works there also offers haircuts if you need one!
