Some places in Central or TST may charge $3 (or close to it) for a bowl of noodles, but I doubt you'll find any with a portion that small.
Their "shui gow noodles" have only 3 shui gows in it, and I could finish the whole thing in 2 minutes.
Anyways, I wasn't really complaining. I actually went eat there last time with my mom, and she explained to me that Mak's portion is actually the "right size" for wonton shops in the old days, as wonton or shui gow noodles is really not a full meal. They're supposed to be just for snack. Anyways, the portion size went up everywhere, and Mak's holding its tradition.
Anyways, there's a noodle shop right across the street from Mak's, and it's also pretty good. Slightly cheaper, bigger portions. But it's not as famous.
