Flowers in the Window

As I was walking past a restaurant, I spotted huge bouquets of these beautiful flowers. The restaurant manager saw me taking photos through the iron bars and invited me inside where more bouquets lined the entryway. I asked if they were lilies, and he said no, they are called donatelas (don't know if this is the correct spelling). There were also yellow ones that had a different name, but I can't remember it. 
I'll soon be going there for lunch!
