D'previlege at Oscar St is full of young Viets. Altho i've stopped going when they jacked their price to $50/30min.
Also you can try Pink berry at 22 Thomas st. Young talents, avoid Mon-Tues tho as only Thais.
Thats about it. Chatswood RNT scene is dying. With the new shop at Thomas st closed down by council about 1 month ago.
