Haven't tried Greek food in a while, so decided to visit a relatively known place called "Santorini". It's located in the hub of international/exotic food, Itaewon (Line 6). Come out from exit 3, walk straight until the end of the street, and you you will see it.
My friend and I tried the Gyros and the Pita bread, which apprently is one of their must haves.
The place was better than I expected, it was very blue and white, going with the Greek theme, the food was definitely filling and the price was customer friendly.
For those who want to go Greek, I definitely recommend you to try it :D
