I have to say the prawn mee at Hong Heng is pretty good and satisfying.
They normally sell out before the stated closing time of 8pm, sometimes even by late lunch. So go early to avoid disappointment.
I would recommend getting the $5 portion, which should be just enough for a big eater. Otherwise, they have $3 and $4 portions as well!
Was it really Michelin-worthy though? I wouldn't go that far. If it really was Michelin-worthy, then why the heck didn't its neighbor Jian Bo a few stalls down get recognized too?
