Pretty bottle,
Sorry for late reply. The hawker used to sell deep fried fish balls after 11:00 p.m. In the Lunar New Year Holiday (1st to 3rd days of Lunar year), owing to the Hawker Control Officer will let hawkers free (because they need to 吞 pot), the hawker will sell food after noon.
The costs is now $10/bag with approx. 15 fish balls. You may try it but be alert to the bad guy in the midnight time
