Hey I recently went to Korea and live in America and was wondering what it may take to open something like a small taco/mexican food restaurant in Seoul. I really loved my time in that country and just want to invent a reason for how to come back + make some profit with some of the knowledge I have. So how easy/hard would it be to do this? I'm a total newbie and just need to get a baseline of general knowledge.
