What are the best takeaway restaurants in Nairobi?

Hi All, We have just launched our online food ordering site in Nairobi called happymeals, where you can order food from all kinds of local restaurants, and we would be more than happy, if you know of any good takeaway restaurants, that we should know of, so we also can provide food from them. It doesn't matter what type, it could also be cakes, beverage, a delicates shop, you name it. Thanks Marie
