A few things stand out about Altius:
1. Altius does a fabulous job with service. They start off with some complimentary spiced popcorn, an amuse bouche, and some bread, and they finish by giving you a mini-dessert to go in a bag. Sometimes the little things count for a lot.
2. The VIEW. If you get seated near the window, count yourself lucky, because it's probably the best view in Pittsburgh. We came on a clear evening and walked around the sleek dining room to take some pictures while we waited. The restaurant extends into the cliffs of Mt. Washington, and it is gorgeous!
3. The Chilean sea bass. This was my favorite dish of the night by far. Beautifully presented, perfectly prepared, melted in your mouth and went well with all of its complements. I will definitely remember this dish for the next time I come back.
Given both the food and the views/service, Altius deserves 5 stars. :)
