Since it generally comes up on the chat board a few times a year.....

Here is the contact information for Dr De Guzman. He is the one always mentioned for diagnosing and treating AC STD's.

It is located between Aphrodisiac and Cotton Club. But since bars change names so often in AC, this may or may not be helpful.

It is just a little ways down from R&B, which seems to have been relatively stable recently.
