Not sure if this has been mentioned, but at the Eternity Bar on Illium you can purchase a Mystery Drink from the kiosk.  It gave you that woosey effect after drinking it, and the old Matriarch bartender looks a lot younger, heh.  Had to do a double-take to make sure her face actually did change.  Can't figure out how to get a screenshot in-game otherwise I'd post the before/after!

Really? I didn't notice that her face changed. I will have to go back there and check it out. Funny that they included that.

Awesome if true, I wonder if the same happens with Chakwas when you get super drunk with her.

Her face changed?! I remember her saying no sex coz she'd just cleaned the bar but I didn't realise that happened too!
