Cafe De Oasis Chiang Mai is the city’s best coffee house as it has an air-conditioned room, water features or the funky interior and a garden full of plants. They serve a variety of quality coffees and iced-teas, similar to what you get in Wawee or Black Canyon. There is also an excellent range of tasty desserts and cakes to keep away the hunger pangs. They have a small food menu, which includes breakfast.
