Vampires!

I vant your blood!

Corner of Pilchard & 48th and Pine & 49th, Draper's Tavern

You drink the Blood.
The barman says "The closest shop to here is White Light, right by Octopus and 36th. I do wish those damn magic shops would stay still for a while."

You drink the Brandy.
The barman says "Don't tell anyone you found a secret door - otherwise it isn't secret any more."
