People tend to check in during these times:
The best stocked Korean supermarket in London. Well presented and easy to navigate. They have anything you'd imagine.
Went here on a Sunday and it wasn't as busy as other Korean food marts. Great selection of fresh produce and household products. My mum loves the frying pans. They even stock a few KPOP CDs now :)
Great selection of fresh seafood.
Aquarium! But alas no mangosteens :(
Korean Takeaway service at weekend-they cook outside
Live fish at the back and most fruit half the price of tesco... And better quality!
