Stalking Bedok Interchange Hawker Centre, I circled the food stalls a few times. Passed New World Mutton Soup a few times but didn't stop because I didn't smell any gaminess 羊膻味.
Second time having lunch at Tien Lai Rice Stall - it is actually a roasts stall serving roast pork belly (sio bak or siew yok), char siew, and roast duck eaten with rice.
Zion Road Big Prawn Noodle is actually the sibling stall of Adam Road Big Prawn Noodle. Both the Zion Road and Adam Road stalls are on the Singapore Michelin guide Bib Gourmand list.
