This famous place for selling Cheese pizza is very nice, unique and affordable.
They offer a set meal for 19800won, where u get a large cheese pizza and a pot of ramen, then a choice of kimchi rice or korean rice cake with cheese. After the meal, you get free ice-cream as well. The highlight is the cheese pizza, really cheezy with a sweet syrup sauce for dipping.
I arrived at 2.30pm on weekday where the crazy lunch crowd is gone. The place closed for break around 3-4pm, so they locked us in and we can have a long quiet meal without any urgency.
