The day I met Camille in Seoul, we discussed our culture shock, or lack there of. I said I wasn't surprised how quickly I adapted, given how developed Korea is.
But she had an interesting comeback. She said nothing is ever actually the same as it is in Canada. Many fast food restaurants offer burgers sandwiched between two "buns" of moulded, sticky rice.
Dunkin Donuts is the only place I can get a decent cup of coffee for under 2USD. Koreans like their coffee chilled, and usually from a can. When asked, "cold with sugar?" I corrected the server: "you mean cream and sugar?" No... cold. Heard her the first time.
Hot or cold, expect a straw.
Green tea donuts? Red bean Bismark? Rice cake? Dunkin Donuts has it, hot from the oven.
