On a cold wintry day, this is a very good place to go. The Korean pancakes are probably by far my favorite thing here. I love the brown sugar pancakes when they're hot and steamy. I don't live near Koreatown and would still make the trip over because they are THAT good.
The little walnut cakes are pretty good too. When they put it in a little bag, you're not sure which flavor you're eating (if you choose a mix of them) so each bite is a surprise.
I'd come again and eat the walnut cakes but what I'd make sure I have stomach space is ALWAYS and FOREVER the hotteok. Grocery stores sell the pancake mix for this (including the filling and all) but I can never squash the pancake to be as flat so they never are as satisfying to eat. Stop wavering (if you are) about coming or not, just go already ;)
