Funny thing about Luma, I went to Luma in Mt. Lebanon and the restaurant was great the food was good and the staff was attentive although I will say that the restaurant was a little bit expensive for what you get. But all in I really liked the place.
However, I can not say the same at all about this Luma. The prices were high, the food was not great, the service was average at best. While nothing about the meal stood out as horrible, when I spend $70-100 (in Pittsburgh) I expect to get a lot more.
As a side note, I found out that the two Lumas are actually under different ownership.
My advice, skip this luma and head out to Mt. Lebo and give it a try
