Almost 40 members of the Golders Green community attended a day of learning on Monday, which is a public holiday in the UK.
The initiative was a joint project of the two Anash shuls in the area, Kingsley Way and Heichal Menachem.
Heichal Menachem hosted the event, where a full breakfast was served after shacharis, which was followed by three shiurim.
Rabbi Yitzchok Meir Hertz, Rosh Yeshiva and Rov of Anash in Golders Green, questioned if one may ask a non Jew to turn on an air conditioner on Shabbos.
Reb Refoel Marelus, the shaatnez tester of Golders Green, gave an overview of hilchos shaatnez, before demonstrating practical problems with suits bought off the shelf, and Dayan MD Elzas, head of the world renowned Frederation Kashrus Authority (KF) explained brilliantly the concept behind allowing or disallowing certain food colorings used as ingredients.
