About the coffee: are they serving it before 11am? As an American in Seoul in 2018, I could certainly find coffee... but rarely early enough to assist with awakening. Even the Starbucks held off opening until 10 or so.
Also, pro tip: Use Naver, not Google Maps, to get around. It is an amazing search engine and well-optimized for English-language use. It's also much more helpful on the subway than any Google experience on any metro I've ever used.
Makes me want to return to Seoul.
