Bong Ja-ne (봉자네) is a pretty well known tent restaurant (Pojangmacha) in Ichon. The woman has been in the location for over 4 years but she had a street cart for 15 years.
Here is her refrigerator full of fresh meats and seafood. She has regular Korean drinking food fare such as grilled eel, fish cake soup, sundubu, and fried oyster.
My favorite are the fried oysters battered in egg. THere are a few pieces of battered pumpkin and peppers here as well.
Here is a review in Korean.
