Cafe Bizou was not making it in Santa Monica, and sold the place to Alan Zaas, who was granted the use of the name Bizou Garden, yet not their own Cafe Bizou name. Different operation, yet probably overlapping menus.
Where are you getting this info? I work in the Water Garden and it was open as of a few days ago. I also just called to ask what the soup is today and they answered the phone, though I think she called it Bizou Garden.
