I passed by this place several times and its always full house.
It serves this traditional HK fare, cart noodles. On the menu its called rickshaw noodles $4.90 with some ingredients already thrown in so you don't have to choose. Add $1 for dry mee.
It turned out to be really good, the soup too. The portion is really small, so you should add side dishes to make it a proper meal.
I added fried wantons, so this is like wanton mee.
