Saw a thread a while back about AMP recommendations which mentioned 1132 Sansom St.  I think its 1112, as I drove by today to check it out.  I then Googled said address and came up with this tidbit:
"
Talk about deja vu. Vice cops found themselves in familiar territory Jan. 11, when they busted a Korean prostitution ring at 1112 Sansom St. It was the 19th time in the past 13 years that an investigation had led cops to the same seedy Center City massage parlor, said Narcotics Chief Inspector William Blackburn."
