I went to Blue Post with a couple for friends for lunch. It was my first time there and I didn't know what to expect. The garden just outside the restaurant has a spectacular view of a waterfall. I found this place very Kenyan. I don't know how to explain it really. There was a 2 man band playing kenyan songs, mostly mugithi.
We found the service painfully slow and when the food finally arrived it was quite honestly not worth the wait.
It still is a nice place to just chill with friends and family on a Sunday afternoon. They have a coffee shop a restaurant and a bar so there's something for everyone. There is also enough space for kids to play.
