Popular Los Angeles Italian restaurant Pasta Sisters is offering a $5,000 reward to have their grandmother's diary safely returned after they shared in an Instagram post that their safe was stolen in the middle of the night over the weekend.

Inside the safe was their grandmother's precious diary full of "recipes, life tips and her memories written in Italian." They asked for its return and called on the public's help as the diary is the only thing they have left from her.

Pasta Sisters encouraged the anyone to share information regarding their grandmother's lost diary by contacting them at info@pastasisters.com.
