Health department officials are urging patrons who ate dessert at the West Village restaurant between the dates of March 23 and April 2 to get vaccinated against the disease. The restaurant owner estimated that approximately 450 people ate dessert during those dates.

"This isolated incident has affected an employee who is no longer on the premises. That employee traveled to Mexico and was infected with Hepatitis A," the restaurant's manager, Manny Solano, told reporters Friday night.

Solano said all the restaurant's employees will be vaccinated by Monday.

The health department says currently no patrons have been reported to have been infected by the disease.
