yeshiva ohr elchanon chabad, the rosh's minyan.
9:15am to 7:25pm. With a 45 minute Break. The best part of the minyan is mariv yom kipur night, which takes well over an hour but after mariv the chazan finishes the whole tehillim in about 50 min.
It was the rosh's "ufruf", but bochurim waited till after yom kipur to throw candy at him. (by a second wedding you don't actually have an ufruf..)
