File this under something new and different to try this weekend: NY Hearts is a love story set in Park Slope that unfolds over audience members’ mobile devices as they travel throughout the neighborhood, stopping along the way at locations that are integrated into the plot. Part walking tour, part theater, part Once, and part Sleep No More, the unique self-guided experience, which follows the saga of two struggling musicians who fall in love, is running this weekend and next. The $25 ticket price includes drinks and other surprises from places like Babeland, DeLuxe and Bar Toto, which are featured in the story. Meet at Grand Army Plaza at 2pm for the three-hour immersion, and you will definitely have something interesting to add to the Monday morning office conversation.
