Altius is astounding. We went here for a celebration on a cool day in March. The sun was shining and with the entire side of the building made of windows, there wasn't a bad seat in the house. Pittsburgh was on display!
The staff was friendly and incredibly helpful in deciding options. I ordered the Salmon and I still dream about it.
I suggest Altius for a special night out, either with family, friends, or a significant other. If you want to feel high-class, go to Altius.
