I am really enjoying the guidebook in the run up to my trip to Ethiopia in October!
I was wondering if you were aware of the Addis Eats Food Tour (http://addiseats.com/)? Addis does not seem to have many (or maybe any) options for tours in english that are not incredibly touristy and this seems like a really cool option! The tours take you to restaurants that are away from the tourist traps and are led by a young U.S. citizen who has lived in Ethiopia for what seems like a while now. The website itself is also incredibly informative about Ethiopian food and traditions–really useful!
