I could literally go to this place every day (I nearly do).
Let's start with the atmosphere:
Colourful, with hammock chairs on the patio, and comfy sitting indoors, free wi-fi and just generally relaxed but spacious place, Arté Café wins hands-down for the atmosphere.
Food (Breakfast, Brunch & Dessert)
Between my husband and I we've tried:
Chocolate and Banana Crepe
Ham, Cheese, and Egg Crepe
Chocolate and Walnut Cake
Chocolate and Orange Cake
And here is the thing: every single item was PERFECT.
The café is owned by a couple, Juan (Columbian) and Marie-lys (French). Marie-lys is the chéf, and she lives up to the French reputation for being a fantastic cook. Her food looks great, and tastes even better.
Juan is the Barista, officially certified in France. His coffees are a work of art.
Arté Café should be on the MUST TRY list for any visitors to Banos, and once you go there, you will go back again :-) I might even see you there if I am still in Ecuador!
