(Today’s Halacha is an addendum to a previous Halacha, "Is it Permissible to Have a Seuda Inside a Beit Kenesset," posted on November 18, 2005.)

The Gemara in Masechet Beitza (24) cites the comment of Rav, "One should never withhold himself from the Beit Midrash for even a single moment." As the Gemara records, a Rabbi once issued a certain Halachic ruling in the study hall one evening, and the following morning, after reconsidering the question, he reversed his position. Some of the students who had heard his ruling the previous night were not present in the Beit Midrash that day, and they were therefore left with an erroneous conclusion on this matter of Halacha. Rav therefore urged students to ensure to be present at all times in the Beit Midrash, so as not to miss any material taught during the study sessions.

The Rashbesh (Rabbi Shlomo Duran, Algiers, 15th century), in Siman 274, applied this remark of the Gemara to explain the practice of Reish Lakish, recorded elsewhere in the Talmud, to drink while studying in the Beit Midrash. Although the Gemara comments in Masechet Megila that one should not eat or drink in the Beit Midrash, Halacha would permit doing so in the interest of preventing "Bittul Torah" (lost learning time).

Accordingly, Chacham Ovadia Yosef, in Yechaveh Da'at (3:10), rules that one should not eat or drink in a Beit Midrash except to avoid "Bittul Torah." Thus, for example, he writes that a "Se'uda Shelishit" may be held in a synagogue if words of Torah are spoken at the meal, such as if the Rabbi delivers a speech. Indeed, this is the prevalent custom. Likewise, in Halichot Olam (vol. 1, p. 264), Chacham Ovadia rules that refreshments may be served at a Torah class held in the synagogue. Since going elsewhere to eat or drink would entail "Bittul Torah" in these situations, Halacha allows partaking of food and drinks in the synagogue.

It must be emphasized, however, that other than in situations of potential "Bittul Torah," one may not eat or drink in a synagogue Sanctuary or in a Beit Midrash, due to the sanctity of these areas. Guests at weddings held in synagogues occasionally take drinks or hors d'ouvres into the synagogue's Sanctuary to eat or drink. This is strictly forbidden; one must respect the sanctity of a synagogue and Beit Midrash by refraining from eating or drinking in these areas, except in the interest of avoiding "Bittul Torah."

Summary: Halacha permits eating and drinking in a synagogue or Beit Midrash only when this is necessary to avoid losing time from Torah study.
