New Woey Loy Goey
You must down a short staircase from Jackson Street to reach this basement-level restaurant. The restaurant has had several owners over the years (it has been open for over a century), but it continues to serve homestyle Cantonese cuisine at unbeatable rates - many of the meals are under $10 per.
You could order anything on their extensive menu and be satisfied, some of the highly recommended dishes are steamed pork hash with salted fish (probably the juiciest giant meat patty you'll ever eat), salt-and-pepper prawns-in-shell with a spicy tingle on your tongue, and roast chicken stuffed with glutinous rice. Try one of the clay pot meals, such as salted fish with chicken and eggplant or chicken and roast pork, which are always boiling hot and full of umami.
