This is one of my favorite fruit and vegetable stands. They sell everything by the plastic basket so it's really easy to tell how much something costs. You can find everything there; peppers, bananas, persimmon, apples, oranges, cucumbers, potatoes...I could go on.
When you figure out what you want all you have to do is bring your baskets up to this guy. He then puts everything into plastic bags. He also might strike a deal with you. Last time I bought $4 worth of oranges and red peppers and he asked me if I wanted a huge bunch of banana for $1 to make it an even $5 bucks. I was like yes please!
Here are some apples and tomatoes in baskets. It's practically like the farmers market though it's pretty typical to find one of these little stands on most corners in Seoul.
