Nancy Olsen, owner and executive chef at Boulevard in San Francisco was interviewed for Haute Living. When she was asked who her most surprising customer was, she replied:
Keanu Reeves came here a lot when he was [filming Sweet November]. He entertained and had guests. He usually brought a party of six. He always made his own reservation, and he always was the first to arrive.
