By day we take care to follow this order: Make Kiddush, then daven Mincha, and after that eat the festive yom tov meal.1

The Baal Shem Tov used to eat three festival meals on Acharon Shel Pesach.

The Baal Shem Tov called the (third) meal of this day Mashiach's s'uda (the "festival meal of Mashiach"). Acharon Shel Pesach is the day for Mashiach's s'uda because on this day the radiance of the light of Mashiach shines openly.

In 5666 (1906) a new procedure was adopted for Pesach in the Yeshiva Tomchei T'mimim in Lubavitch: The students ate the Pesach meals all together, in the study hall. There were 3102 students present seated at eighteen tables. My father the Rebbe ate the festive meal of Acharon Shel Pesach with the yeshiva students. He ordered that four cups of wine3 be given each student, and then declared, "this is Mashiach's s'uda."
