Thong Heng is an oriental supermarket in Headington, and I have to say, one of my favourite places to shop. Its perfect for finding all the varieties of sauces and flavours you need to cook chinese/thai/vietnamese meals properly and its really good value for money. Its cheaper to but soy sauce here than in a regular supermarket and there are so many brands! Also we buy our rice here in bulk, which works out much cheaper than buying from Tesco/Sainsburys and its actually flavoursome and sticky(if you cook it right that is!) As well as the dry food stuffs, they also have a wide variety of frozen foods, I particularly like the frozen raw prawns and dim-sum buns. Great to keep in the freezer to rustle a quick dinner up with. They also stock a selection of exotic friuts vegetables which all look fab even though I have no idea what some of them are. I really enjoy browsing the shelves for new things to try, new flavours and weird and wonderful things too!
