Forget Starbucks or Dean & Deluca, locals have been coming to chat over coffee at On Lock Yun for over 80 years. With its inconspicuous façade, this cozy spot has forged a strong following that come for a cup of joe and the Thai-style American breakfast, and stay for the old-world atmosphere. The no-frills décor only adds to the charm, with wooden cabinets filled with tins of various flavored powder products from the 80s and all manner of condiments. Drinks like coffee and milk start from B20 and American breakfast from B40.
