Streamer Coffee Company, Shinsaibashi
Despite it's name, it has nothing to do with online streaming! Streamer Coffee is a hip spot in the middle of Shinsaibashi, Osaka's famous shopping and entertainment district, close to the Dotonbori river. The coffee here is great, and the staff is super friendly. You can bring your laptop here and sit in the sofa, stools or long table. Most of the seatings have power plugs, and there's WiFi here with OK quality. A lot of young folks stop by, so expect a somewhat loud environment.
