Seoul is lovely but still has some challenges for nomads. Korean food is great, but most restaurants are used to serving groups, or at least couples. Many times you'll simply be refused service entering a restaurant alone. Unlike Japan, eating alone is stil frowned upon in Korea and mostly impossible. Exceptions are of course expat areas like Itaewon which are more used to it. Also outside signage and menus are mostly still in Korean, without any English translations generally. Even if you learn the Korean characters, you won't know the words, so this makes it impossible to order. This is slowly changing though, especially in hipster areas. You might ask "why does this reviewer care stuff is in English or not, they're in Korea, what does he expect?". Well, it's 2018 and Korea presents itself as an international country, English should be the default sub text. There's more challenges, it's very difficult to meet Koreans, you'll always be seen as the "token" foreigner in social groups. This is understandable and to be fair it's much worse in Japan than Korea. Unless you're in expat areas, you'll feel fairly isolated because Koreans will generally avoid you for fear of having to speak English. This makes it a potentially very lonely experience for any nomads. This is kinda vicious because Koreans look down on people that are alone. Hence the group-eating thing. Solutions to that? Come here with a group of friends. You'll have a MUCH easier time.
