If you're craving an In-N-Out burger, you can get a rough approximation at Thunder Burger in Itaewon. I was pleasantly surprised. The burger is pretty similar, minus the annoying Thousand Island Dressing.
Get off at Noksapyeong Station. Take exit 2. You'll have to cross the street (the crosswalk should be to your right if you're facing the traffic). Then, walk up the street for a bit. It's next to the TACO restaurant.
