Tomorrow night, Friday night, will be the long-awaited attempt in Tel Aviv's Hangar 11 to set the Guinness world record for the largest Shabbat dinner, with 1800 attendees.

The dinner event has been put together by an organization called White City Shabbat, consisting of local Tel Aviv residents.

Interestingly, while just about every article (that I could find) talks about it being run by White City Shabbat and talks to the organizers (e.g. Indiegogo campaign, Jpost, INN, Facebook event page, Algemeiner, etc.), Maariv/NRG reports the dinner as being organized by Chabad of Thailand.

Anyways, best of luck for the event and I hope the record gets set smoothly!
