Most Koreans drink a lot of water. Filtered water machines are everywhere, from restaurants (where it is self serve water) to just outside my office. These machines are really cool as they filter the main waterline (no need for a big tank) and they offer electronically cooled and heated water. Very fancy. When dining, it is customary for on person to get water for everyone at the table. In public one must never pour a drink for yourself. Always pour and offer drinks with both hands and serve the oldest person first (age plays a large role in social hierarchies).
Apart from water, this country loves two things, alcohol and coffee. Now coffee here is not what you would expect. Sure I can get a normal Americano roasted and dripped coffee. There is a plethora of coffee shops around every corner. But real roasted coffee comes at a steep premium. A simple cup of coffee can run anywhere from $3-7. So to save their hard earned (and trust me it is very hard earned) dough, Koreans drink a lot of instant coffee. Thankfully this is some of the best instant coffee I have ever had. I mean they have perfected the instant coffee. Whether it comes in a little pack, a tea bag, or a large bag this isn't your grandpa's Taster's Choice.
So as I finish this post, nursing an overpriced bottle of Hoegaarden, I can certainly say, there is no shortage of things to drink in this new country of mine. I haven't tried it all (so perhaps I will revisit this subject) but I have yet to try anything new I have found too terrible to drink. And if I had any word of advice to anyone else. Beware the soju, and try the aloe. It's ok to like it. Trust me you are "aloed". (Sorry, my dry humor and cheesy wordplay is lost on a nation who can't understand me.)
