老三kway chap is located at ang mo kio ave 3, one of the stalls at the coffeeshop a few shops away from Melben seafood. There was a queue of about 10-15mins when i arrived at about 12pm-ish on a Saturday. The kway soup is a little more oily than the normal ones i have had around in Singapore. The kway is of medium size and you can taste the slight thickness of it. I ordered pig skin, 大肠头, eggs and braised meat. The pig skin is chewy and the 大肠头 was chewy too and not too flavourful. The braised meat has more lean meat than fatty.
