According to the Kosher Miami hechsher, Pistachio Grill located at 740 41st Street in Miami Beach is NO LONGER under Kosher Miami supervision and certification.
Miami Kosher has not been asked by the new owners to give certification to them, and it is uncertain how they plan to operate the restaurant, i.e. Kosher or Not Kosher.
For now, one must assume that the restaurant is not Kosher.
