Boonsik is quite unique relative to its neighbour restaurants as it specializes in mandu (Korean dumplings) and kimbap (Korean rice roll, similar to sushi), among other specialty dishes. This family restaurant is so low key that you really have to be looking for this place. But beyond it's unassuming store front awaits friendly service and delicious Korean food.
My companion and I both had eyes bigger than our stomachs and we ended ordering 4 dishes: fried mandu, bulgogi kimbap, pork bone soup, and kimchi stew with pork. We also received 4 side dishes. I HIGHLY recommend the traditional kimbap, having tried all variations. It's simple but delicious. The fried mandu is always a win as well. Just wait for it to cool as it comes out piping hot.
Compared to the appetizers, the kimchi stew wasn't striking - the broth just wasn't my favourite. My companion really enjoyed the pork bone soup though; the pork bones were piled high, along with a healthy portion of potatoes.
This is true gem in the Ktown area!
