Mullen has linked with restaurants all over Boston to donate $1 to famine relief every time participants eat a meal there, as part of the 50/50 Good project, the famine relief effort co-ordinated by Made by Many.

With The Good Belly Project, every time participants eat a meal at a participating restaurant, they take an Instagram picture of their food and share using the hashtag #goodbellyproject. For every picture they take and tag, a donation will be made.
