Patti,
Le Bar Bat was actually the spund studio where Robert Cobert recorded alot the Dark Shadows sound track. I am not exactly sure how many years this building was a recording studio but in the mid 90's it became Le Bar Bat. Several NYC DS festival events/dinners were held there . It's kind of ironic that the studio where the DS music was recorded became a gothic restaurant/bar.
For the most part , I think, the actors used to hang out at the Brittney Du Souir after work. It was in existance through the 80's. Not too far from the studio itself.
