I am not fluent in Korean. The only thing I learned while out there was: 1. Hello 2.Thank You 3.Coffee
While near big cities there were people who spoke some English but not much. While in the country it was 0 chance someone spoke English. They would just keep talking Korean to me and smile.
I used Google Translate with a photo recognition feature. I would take a photo of the menu, use the translate and then point to what I thought I wanted.
Also I would take a photo of the menu and in my annotation circle what I want and show them my phone
Also I would type into the translator things like: Please help me choose breakfast and show them the translation
Also 7Eleven or Nice2CU stores were great for free internet and easy grab to eat. I would buy onigiri or kimbab right there and eat it outside at a picnic table
