It's kinda a bait and switch central too. 35 yr old chinese woman post as 20 yr old japanese or korean. The boob size advertised is usually a tell-tale sign, bigger then 34C? expect to see an old woman with saggy boobs.
That being said, I have a few good encounter with micros around joyce skytrain, just search the last 4 digits when you are in doubt, even if the last good review is like 6 months away its still good, quality of the girls working in the same micro in joyce area is usually consistence.
