Three choices always on the menu: red bean paste with walnut, mashed potato with walnut and red bean paste with almond. my Korean friend who introduced me to Hodo Kwaja only gets the original red bean with walnut.
Having had many Bungeoppang (red bean cake, really the same thing but fish-shaped, instead of walnut shaped) before in Hong Kong, Tokyo and Korea, I would say Hodo Kwaja measures up to expectations.
one word o advice though - you'd want to eat the cakes as soon as you buy them, they turn stale within 5 days. but that shouldn't be much of a problem...
a must-purchase for first time Koreatown explorers.
