It's a Greek type of font but which one?

Also, this is not the proper height. This is on a sign laying on the awning of a building so the view is at an angle and the letters are taller than they appear.

I think because this is signage the person who made it did it by hand. It looks like they grabbed some of the letters (RB) from the Foreign look - Roman/Greek pages and the only time I have seen that O was here on dafont in Chizz. But I would consider marking this "Not a Font."
