Last Sunday, I was at KK Market (aka Tekka) and happened across a greengrocers called Chia's Vegetables Supply. In addition to the usual kailan and chye sim, they stock exotic vegetables that are more likely to be found at gourmet supermarkets like brussels sprouts, matsusake mushrooms, baby spinach, as well as herbs like rosemary and thyme. Prices are cheaper than what supermarkets would charge. Mr Chia rings up purchases with possibly the only cash register in the entire market. There is music too, chosen by the son Victor Chia and I have to say, bossa nova was the last thing I expected to hear at a wet market in Singapore. That is, if one can hear the music at all, because the Chias have many customers, and it can get noisy. Go early if possible.
