Don't let the low prices fool you. The food is good.
I came here on a Sunday, around 5:30pm. The place was packed, so we knew we had made a good choice.
We got seafood pancake (a full plate of pancake with veggies and seafood; $6.50), bibim naengmyun (spicy cold noodle; I think it was $7.50) and spicy kimchi pork stir fry (this dish is served with a bowl of rice on the side; this was around $9).
They also gave 6 appetizers (aka "banchan").
We were full and the food was good. My only complaint is, nothing was actually spicy, and all the spicy things are actually quite sweet and barely spicy. But I understand that they have to please the masses. I guess you could ask for extra spicy if you really needed it (not that it said that on the menu or anything).
Also, the service was quite good. Friendly, and quick.
The place was busy, both when we came and exited, so it must be quite popular. The washroom was actually not bad.
