Nana Coffee Roasters is one of Bangkok's most decorated specialty-coffee names, and its Ari flagship is the one to visit — a glass-and-timber villa wrapped in greenery that feels part greenhouse, part living room. The bar pours more than thirty single-origin beans, all roasted in-house and served with tasting notes across siphon, pour-over, and espresso.
It also does a strong creative brunch, which makes it a natural first or last stop on an Ari café crawl. Come early on weekends; the garden seating fills up fast. On Soi Ari 4, about a ten-minute walk from Ari BTS.
