My crystal ball is broken, and I don't have all of the facts.

This is a Q&A forum. You have not asked a question. You have simply ranted about what happened.

The expense of suing, and retaining a doctor to testify that your illness was caused by the strawberries, along with the lack of damages, means it...

Depends on your warrant, if any...............................

Your question isn't really can you sue. Anyone can sue. Your question is can you win. None of us can fully evaluate your claim in a short on line...

If you want to spend hundreds of dollars to sue for a meal, have at it.

None of us can teach you to practice law. That is not what this site is for.

It is perfectly legal, just as it would be legal for you to decline and go elsewhere.

If he takes you to court he will be granted some form of custody and visitation.

You will need a physician to testify that the surgery team deviated from the standard of care. You will need a lawyer to do that.
