Special Kosher Mitzvah Meal

"Every Mitzvah that they accepted upon themselves with joy ... they still perform with joy." (Talmud, Shabbos 130a) Rashi interpreted this to mean that a festive kosher meal should be prepared. Included in this meal should be challah and kosher wine. It is customary not to issue a direct invitation to the ceremony, for one may not refuse to attend. To do so would be equal to turning down the opportunity do perform a mitzvah. At the conclusion of the meal, Birkas Hamazon, the grace after meals is recited with special blessings for the child, parents, sandek and mohel.
