Scenario:

A potential client believes she got food poisoning from a local Orange County restaurant after eating an Ahi Tuna appetizer. Within 24 hrs of dining. She fell ill and went to the emergency room. She tested positive for specific bacteria found in certain raw foods. Her friend, who shared the appetizer with her while dining, also fell ill, but did not go to the emergency room.

Draft a memo addressing whether the potential client has a valid cause of action against the local restaurant, and if so, what legal theories may she assert, citing at least 2 secondary and 2 primary sources in the Draft.
