The Yemeni population in San Francisco, Oakland and Fremont is small but significant. They run many of our grocery stores and now, increasingly our coffee shops and restaurants too.
I'm a big fan: I love the food the most (most Malay and Indonesian Arab food *is* Yemeni-derived) so there are lots of similar flavors that remind me of home.
