Klausenberger Rebbe - Nacheim When Eating On Tisha B'Av?
The Rema (OC 557:1) says that if someone needs to eat on Tisha B'av they say Nachem by Birchas HaMazon before U'Vnei Yerushalayim.  The Mishna Brura says that although we only say Nacheim in Shmoneh Esrei by Mincha, when eating you say it every time you bentch, even the night of Tisha B'av.  He also brings the Vilna Gaon who says that one should not say Nachem by Bentching because Chazal made it specifically for Tefila.

The Piskei Tshuvos brings from the Kaf HaChaim that saying Nachem, if not necessary, would be a Hefsek in Bentching and therefore it is preferable to leave it out or say it later by the HaRachamans.  The Klausenberger Rebbe (Divrei Yatziv (OC 2:244) argues and says that Nachem is definitely not a Hefsek even if you don't need to say it.  The reason is that it talks about the day of Tisha B'av and is therefore part of the day.  

More compelling however is that if a person does not say it, he says, it seems like he does not care about the Aveilus of the day.  Saying Nachem shows that he is mourning the Churban.  It will also remind him not to indulge in fine food, but only to eat what is necessary for his health.  Therefore he concludes that even those who hold that you don't say Yaaleh V'Yavo by Birchas HaMazon on Yom Kippur, still agree that on Tisha B'Av Nachem should be said.
