Finally I got him to walk down the alley only only once after you have dominated/dementated him. And I made him talk there again for a bit of dialog fun, and no risk of blowing the masquerade...
He has some interesting free lines I could use there.
Of course you still can just grab him there and feed this way.
Since he's only dominate 1, every Malk, Tremere, or Ventrue can use him this way. Plus Brujah and Toreador with Presence 2
P.S.: Good chance I can make him a male blooddoll as well... At least for the "better" kind of clubs like Asp hole and Empire hotel lounge.
Tuesday is Soylent Green day.
