I arranged a trip to the market, the cooking and sharing the meal, through a website called Traveling Spoon. I had a very good time. My hostess was Grace Mwangi , a young Kikuyu woman. She was very friendly, easy to talk to, and of course a good cook. The food was delicious, the conversation interesting. I did this by myself, no one else with us, and certainly never felt a moment's unease. I recommend taking the whole offering (market, cooking and eating) because you get to know Grace a little. A very nice woman. I also recommend taking the option of paying for her to come pick you up. As we got close to her home she several times had to tell the driver which turns to take - his Google Maps didn't get it right.
