There is a shop opposite Kwan Im temple at Waterloo St. There is an auntie inside, and you will see people queuing to wait for their turn. I heard that people are willing to wait for 4 - 5 hours, some came as early as 3am.
I went there yesterday at 6am. Waited about 2 hours for my turn. The auntie asked for my DOB. She is quite accurate in accessing my situation. She also suggested ways of enhancing my luck. I find her quite good. She charge very reasonably, one question is $5.00. You can ask her about anything. I asked about myself, my boy and my girl, talked for about 1 hour, only $15.
