Plaintiff alleges negligence against P.F.Chang’s China Bistro over allergic reaction incident
A severe allergic reaction has led to a legal battle between a Florida resident and a popular restaurant chain. Dianna Miranda filed a complaint against P.F. Chang’s China Bistro, Inc. in the Circuit Court of the 15th Judicial Circuit in Palm Beach County, Florida, on March 27, 2025. The lawsuit alleges that the restaurant’s negligence resulted in Miranda suffering from anaphylactic shock after consuming food containing shrimp, despite her explicit request for a shellfish-free meal.
According to the complaint, on June 11, 2023, Dianna Miranda visited P.F. Chang’s China Bistro located at 1400 Glades Road in Boca Raton, Florida. As someone with a known shellfish allergy, she specifically requested a meal free from shrimp or any shellfish when placing her order. The restaurant had advertised an “Allergy-Free Menu” and assured customers that it could accommodate those with food allergies. Miranda informed the staff of her severe allergy and sought assurances that her meal would be free of shellfish or any cross-contamination.
The staff at P.F. Chang’s confirmed that the ordered food would be prepared without shrimp or shellfish and was safe for consumption by Miranda. However, after consuming a soup served by the restaurant that was represented as shellfish-free, Miranda experienced severe allergic reactions including difficulty breathing, swelling of the face and throat, hives, nausea, dizziness, confusion, and ultimately anaphylactic shock. This required emergency medical treatment involving epinephrine administration and hospitalization.
