This place is a small stall located inside PAT Mart and is almost always operated by friendly ajummas. There are 4 flavours: custard, red bean, black bean, and green bean. They say red bean is the most popular but custard is and will always be my thing. They offer discounts if you buy a combo of their taiyaki. It gets confusing with the pricing but peep my photo for the prices.
All in all, taiyaki is a popular snack in South Korea and I always get me some taiyaki whenever I'm in South Koreatown. It reminds me of some good times I had in Seoul when I was still in school.
One thing I need to know is where in the world is Kevin of Kevin's Taiyaki??
