I think you may be referring to "Cinespace".
Not the greatest screening room in my opinion and expensive too. But good if you need a nice reception area. Also, not a very big screen and poor sight lines. I was at a screening a week ago.
As Michael says, I'm afraid it IS expensive here in LA. And The Gallery is far from the cheapest, although it is a very nice theater and setting.
How many seats do you need?
