Step 1- find ways around as many of the hills as possible. Elevators are allowed.
Step 2- find as many Dunkin Donuts as possible. Try different donuts out, frequently, so as to find new favorites. The donuts here are different than in the States, so you have to start all over from there. (Continue to avoid the ones containing Kimchi, soybeans, tofu, sweet potato, and whole wheat.)
Step 3- find as many Starbucks as possible. Discover that they do, indeed, have the Venti size. It's just not advertised on the board.
Step 4- become addicted to Korean Coca-Cola.
