I have stayed in Tribe Hotel Nairobi from 26 - 29 Jun 2013 and this my review:
1. Hotel design & Interior is noticeably amazing and with good composition.
2. Reception - Needs more training dealing with both the guest and the bell man located two meters from the reception desk.
3. Hotel Main Restaurant - aside from their break fast which is fantastic, the lunch and dinner menu is just bad with exception of their Lobster Roll which really good and cooked perfectly. But this is not good enough as I had to walk to the Village Market (http://villagemarket-kenya.com/), thank GOD it was next door to find good food to eat.
My recommendation next time I will try another Hotel
