As the older lady who served us didn't speak English, we showed her the pictures of the dishes we wanted to order. However, two of the three dishes weren't the ones we had ordered when she came back from the kitchen. Her daughter was very friendly and apologized for the inconvenience, she brought as two bananas as a dessert. All in all good food but nothing extraordinary. Maybe the best part of our meal was the homemade hot black sesame milk, so you should definitely go for that.
Cons: you find cheaper vegan places in Hoi An, rather small portions
