The shop in al nasr (near FFC) is Korean Food center.
They sell kimchi, korean noodles, black mushroom, dried fish & otopus, frozen red bean bun, tempura flour and some other food which I dont understand :).
The store is not too big, sometimes they run out stock at the end of the month. But you can smile if the new stock coming :)
If you need something specific, better call the store : 4360 316
