COEX is like the equivalent of Suntec in Singapore. It has convention centre, exhibition hall and underground shopping centre. Well, Noona and her friend are confident there will be food inside too. 

We did find a restaurant at the corner of level 1. It was already late in the afternoon, around 3PM-ish. So there were nobody inside except for the restaurant's staffs. Good enough for us, at least our food would come out faster. Hahaha.

The restaurant specialises in local Korean food so Noona tried their soft tofu soup (i.e. sundubu jjigae). This jjigae is the clear type and hence it's not red in color. The kimchi is served separately as a side dish. 

Do note that a portion of pancake (i.e. pajeon) in Korea is always big. This is the spring onion pancake and wow, look at the number of spring onion layered on the top of the pancake. Crazy.

Noona has a spring onion overdose now. XD
