I cannot BELIEVE people don't like Red Bean Paste. I will gladly eat anything Red Bean Paste. Yum.
The Walnut Potato ones are good too, but just not the same. A dozen walnut cakes for $3 is the perfect dessert for two - great for stopping in after eating Korean food in the neighborhood.
Bonus is the friendly service. The lady actually giggled when I thanked her with a "kamsa hamnida!"
Walnut cakes are great because they are still rare enough that you can still delight and surprise people with them. Great to bring a little box to a party.
