A spokesperson for Gigi Pizzeria admitted to BuzzFeed News that the reaction so far had been mixed.

"The reaction to the change so far has been mixed," they said.

"We have had an overwhelmingly positive response from many of our loyal and new customers. On the other hand, many of our customers have been disappointed. We hope those customers have a change of heart and maybe even come back to appreciate the very first authentic Neapolitan pizza (one of two recognised by the AVPN) - the Pizza Marinara (san marzano tomatoes, garic, oregano and extra virgin olive oil)."

"Our decision was definitely not one made over night. It was a change for all the right reasons, so we have absolutely no doubts over the new direction."
