This past Sunday I ventured upon a nice little cafe and grocery store that carries some harder to find foreign food items in Korea. The grocery section stocked pastas, sauces, cheese and even Cannelini beans (I have a hard time finding these in Korea). The grocery section was pretty small but for someone looking for a nice selection of cheeses and harder to find Italian items I think this store would be worth checking out.
The cafe portion offered pretty standard coffee drinks and some fruit juices for average prices.
The grocery portion had two refrigerated sections (one for cheeses, sausages and other small foods) and one had imported drinks (sodas, beers and sparkling waters). You could also find a small selection of Italian groceries: pastas, spices, sauces, beans and I even saw anchovies.
I think if you are in the neighborhood it is definitely worth stopping by to take a look into the small grocery, from what I saw the prices seemed pretty fair with what I have seen foreign foods being sold elsewhere in Korea.
