Viburnum davidii ? If so, there needs to be a male plant and a female plant to produce the berries. I had two in Scotland - they were my pride and joy but sadly the cuttings didn't take so I don't have it here
I think I have found it. Look for aronia melanocarpa.
The chokeberry group.
I think it is a better fit.
I have Aronia melanocarpa in my garden...the berries are never this color. They go from green to a kind of dull red to dark purple blue, almost black. Never a bright blue like those in the picture. Also, Aronia leaves have finely serrated edges. I also suspect some kind of viburnum.
