I've been to the Blue Nile many times since moving here, back in '94. I love the food, but we have experienced slow service a few times. My favorite dish is the Ye Siga Wat and the Doro Wat just falls off the bone. I've taken family and friends there and everyone has loved it, though my dad doesn't like eating with his fingers.
I'm not expert but I've been to 3 other Ethiopian restaurants, 2 in the Bay Area and 1 in Sacramento, and so far this is still my favorite.
Pros: good food, very friendly
Cons: no high chairs, sometimes slow
