As for the link between food and politics?
"Karimi says food is a natural place to begin conversations about international relations. 'I don't know if you notice now with the current rice crisis, but even politicians have to talk about food, although that's just in a superficial way, about the farm bill and the gas crisis,' he says. 'Food is a point of departure.''' (Chronicle article).
The Contra Costa Times writer calls it "tasty, funny theatre."
I plan on going next week, and really look forward to seeing a good showing, having good conversations, and eating some good Iranian-Guatemalan-Filipino food (yes, they feed you during the show!).
If you don't live in the Bay, you can check their blog for upcoming shows.
