Crystal jade wanton mee is not bad.
Sunshine plaza has this parklane wanton mee should be good too,
never tried it personally, its opposite Victor's kitchen.
Then there is fei fei at joo chiat place, which I have not
touched in over a year, only the noodles are good, not wanton, not
char siew.
Then there is the wanton mee I have been patronising for over 25
years located at kovan centre, it is Yi Shi Jia Shu Shi. Not the
best noodles, not good char siew, but I like their wantons, it has
a light bitter after taste and the right texture, I always take the
soup one. Expect long queues during lunch, and closed on
sundays.
