One thing that struck me first in my visit to Seoul in January 2017 was the very shortage of English signs around me.On most corners i saw there Starbucks, Dunkin Donuts and other big chains beside smaller independent Korean businesses written in Hangul.In Seoul mostly every thing was written Korean Language. As i do not know Korean , it caused me tension and worry . I suggest all the display / sign boards must be written in both languages : Korean & English .
