We traveled on a day trip with Nairobi Excursion in January 2012. They picked us up at Giraffe Manor and took us to the Kiambethu Tea Farm for the day/afternoon. Then through Nairobi to the market where we did some shopping (super high pressure), and then to a wonderful dinner at Tamarind Seafood restaurant which was fantastic. They then transferred us to NBO for our departing flight. Their price was very reasonable and the service excellent. I highly recommend them!
