O2o First Roast is a roastery cafe in Da Nang that works with specialty beans. It serves single-origin coffees such as Ethiopian Geisha, Yirgacheffe and Sidamo, along with a robusta condensed-milk coffee, and the same beans are prepared as both hot drip and chilled drip. Baristas explain the bean choices and brewing methods and make recommendations, and stickers are sometimes given as souvenirs. Ordering is difficult for those who do not speak English well.
