Beef Noodles at Old Airport Road can be found at Ying Ying, which has the traditional Teochew style, or at J&J which offers different style beef noodles. And it is good!
Located in the sleepy section of Old Airport Road, there usually are not many people around trying this great noodle.
They have a Braised Beef Noodle which they say is their specialty.
Stir it up a bit and it contains Pho looking noodles, which make it nice as it gets coated with the gravy.
