I've eaten (and, for the most part, enjoyed) Ethiopian restaurants in several cities worldwide, and Nil Bleu is a great one. The flavours were a little less strong than in other Ethiopian establishments I've visited, but the quality was solid and the whole experience enjoyable. They put a little more care into presentation than we're used to (from a flower presented on the plate with the kitfo, to an incongruous salad in the centre of the tasting plate, right on the injera). In all, a worthwhile visit.
