I've been here a few times, and it has been excellent each time.
One of my favourite Ethiopian spots in the city, and some of the best lentils I've had.
While they do offer meat, Pero has excellent vegetable dishes - definitely a must-have.
A great thing about Ethiopian food is that you eat with your hands - and when eating with friends, it can act as an immensely personal experience.
I can't say enough about this place. Will certainly be back.
