Se’if 1א׳

אֵין קִדּוּשׁ אֶלָּא בִּמְקוֹם סְעֻדָּה, וּבְבַיִת אֶחָד מִפִּנָּה לְפִנָּה חָשׁוּב מָקוֹם אֶחָד, שֶׁאִם קִדֵּשׁ לֶאֱכֹל בְּפִנָּה זוֹ וְנִמְלַךְ לֶאֱכֹל בְּפִנָּה אַחֶרֶת, אֲפִלּוּ הוּא טְרַקְלִין גָּדוֹל, אֵינוֹ צָרִיךְ לַחֲזֹר וּלְקַדֵּשׁ. הַגָּה: וּמִבַּיִת לְסֻכָּה חָשׁוּב כְּמִפִּנָּה לְפִנָּה (מָרְדְּכַי פ' ע"פ) וְיֵשׁ אוֹמְרִים שֶׁכָּל שֶׁרוֹאֶה מְקוֹמוֹ, אֲפִלּוּ מִבַּיִת לְחָצֵר, אֵינוֹ צָרִיךְ לַחֲזֹר וּלְקַדֵּשׁ. וְיֵשׁ אוֹמְרִים שֶׁאִם קִדֵּשׁ בְּמָקוֹם אֶחָד עַל דַּעַת לֶאֱכֹל בְּמָקוֹם אַחֵר, שַׁפִּיר דָּמִי וְעַיֵּן לְעֵיל רֵישׁ סי' קע"ח, וְהוּא שֶׁיִּהְיוּ שְׁנֵי הַמְּקוֹמוֹת בְּבַיִת אֶחָד, כְּגוֹן מֵחֶדֶר לְחֶדֶר אוֹ מֵאִגָּרָא לְאַרְעָא, וְכֵן עִקָּר.

That Kiddush Be Recited in the Place of the Meal, 7 Seifim: Kiddush [is valid] only [if recited] in the place of the meal (see Pesachim 101a) and in one house. [Changing one’s place] from one corner to another corner [in] the same [room of] a house [is not significant. If one recites Kiddush in one corner with the intent of eating there and then changes his mind [and decides] to eat in another corner of the same room in that house, even in a large hall, he need not recite Kiddush again. RAMA: From the house to the sukkah is significant, like changing from one corner to another (Mordechai). There are those who say that anyone who sees his place - even from a house to a yard - does not need to return and say kiddush again. And there are those who say that it is also reasonable if one says kiddush in one place with the intention to eat in another place. (And see the beginning of Siman 178 above). This is so if both places are in one house, for example from room to room or from a rooftop to the ground (and such is the essence).

Se’if 2ב׳

אִם קִדֵּשׁ בְּבַיִת אֶחָד עַל מְנַת לֶאֱכֹל שָׁם, וְאַחַר כָּךְ נִמְלַךְ לֶאֱכֹל בְּמָקוֹם אַחֵר, צָרִיךְ לַחֲזֹר וּלְקַדֵּשׁ בַּמָּקוֹם שֶׁרוֹצֶה לֶאֱכֹל שָׁם.

If one makes kiddush in one house over a dish eaten there, and afterwards goes to eat in another place, must return and say kiddush in the place where he wants to eat.

Se’if 3ג׳

אִם קִדֵּשׁ וְלֹא סָעַד, אַף יְדֵי קִדּוּשׁ לֹא יָצָא. הַגָּה: וְצָרִיךְ לֶאֱכֹל בִּמְקוֹם קִדּוּשׁ לְאַלְתַּר, אוֹ שֶׁיְּהֵא בְּדַעְתּוֹ לֶאֱכֹל שָׁם מִיָּד, אֲבָל בְּלָאו הָכֵי אֲפִלּוּ אָכַל בִּמְקוֹם קִדּוּשׁ אֵינוֹ יוֹצֵא (מַהֲרִ"י מוּלִין), וְאִם הָיָה בְּדַעְתּוֹ שֶׁלֹּא לֶאֱכֹל שָׁם מִיָּד, וְנִמְלַךְ וְאָכַל, יָצָא (בֵּית יוֹסֵף סוֹף הַסי').

If one makes kiddush but does not eat a meal (afterwards), even regarding kiddush he has not fulfilled his obligation. Rema: One must eat in the place one makes kiddush. However anyway, even if one eats in the place that kiddush was recited, one has not fulfilled (one's obligation). (Mahar"i) If it was his intention to not eat there immediately, and then he went and ate, he has fulfilled his obligation. (Beis Yosef, end of the Siman).
