I'll be brief because there isn't a lot to say.
I was there recently on a Saturday at 9pm, not in the heatwave mind you, and the RLDs of de wallen and singel are a shell of their former selves.
Many windows were empty, and those that weren't had not a lot of talent between them. The very few women I was interested in seeing were quoting €100 for 15 mins. Between the obvious rushed service and real profunctory nature of the whole thing, it was only good as a cheap thrill with a generally attractive woman.
It has neither of those qualities now.
