I don't have much to add that has not already been said. I went with a group of 8 people and we all enjoyed the food. Great variety, really good injera bread, nice outdoor garden setting. This is the third Ethiopian restaurant I've visited in Nairobi and is hands-down the best.
As noted by a previous reviewer, it can be a bit difficult to get a menu for everybody but this seems to be a common thing in Kenya - one or two menus per table even if there is a large stack of menus sitting right there.
One downside that is common to all Ethiopian restaurants I've been to in Nairobi - if you plan to leave soon after eating you better ask for the bill right after they bring the food. It's hard to imagine how it could take so long to get a bill when there was only one other table with customers. But that's just part of the overall experience.
