Chapter 10, Mishna 1

If we say Shabbos Kiddush over wine (sanctifying the day) in synagogue on Friday night, must we say it again at home over our Shabbos meal? If we’ve recited Kiddush and Motzi (blessing over bread) and started eating, and then a bride and groom walk by outside whom we wish to greet, do we need to say Grace After Meal before exiting, and repeat the introductory blessings when we return?
