This is, at nr. 56/58, the Grand Pera. I did not enter, so I take their word for it: "Grand Pera is located at the heart of Istiklal Avenue in Beyoğlu, which has been a center of attraction and a symbol of shopping culture since the 19th century. Offering services to the culture, arts, entertainment, fashion, and gastronomic world, Grand Pera is a new generation lifestyle center that brought one of Istanbul’s most valuable historical buildings, Cercle d’Orient, back to its former glory through quality renovation at world standards and that introduced Emek Cinema to future generations through a sustainable understanding. "

I like that "sustainable understanding". There is so little of it in this world, but they have it. Though it is not clear to me if it's in the cinema only, or all over the place.
