Arbis, the hummusiya location for the Friday, June 25 event, has been using Private Supervision certification since it opened two and half years ago, said Yoav Bakerman, one of the three owners.

Bakerman said he and his partners didn’t like the working methods of the rabbinate.

“It’s a lot of money to use the rabbinate,” said Bakerman. “It was important for us to have a kosher restaurant, and it’s a kind of bridge for other customers.”

Some customers have chosen not to eat at Arbis when they found out what kind of kosher certification the restaurant uses, but they have served ultra-Orthodox and modern Orthodox customers just the same, said Bakerman.

When the new kosher certificates were given out two weeks ago, the hummusiya offered to host an open house to show that “it’s time to do things differently.”
