The CTO of OpenTable has 55,000 restaurants on his app — but he only eats at 30 of them

  • Joseph Essas is the Chief Technology Officer of OpenTable and an Orthodox Jew who only eats kosher food.
  • Out of the 55,000 restaurants on OpenTable, Essas estimates only 30 of them are kosher.
  • Essas told Insider that not being able to use the services of the company he works for is the story of his life – he used to be the CTO of dating site eHarmony and has been married for 23 years.

Joseph Essas is on a special diet.

As the CTO of OpenTable, Essas oversees an app for people to reserve and review over 55,000 restaurants – but as an Orthodox Jew who only eats certified kosher food, he estimates that only 30 of those restaurants are compatible with his religious observance.

“Kosher” means “fit” or “proper” in Hebrew. Jewish organisations like the Orthodox Union work with companies to ensure that the food they produce meets kosher standards, as detailed in the Torah and codes of Jewish law. Kosher restaurants require additional levels of expert supervision in the kitchen.

Insider spoke to Essas at an event hosted by Jew in the City, an organisation dedicated to breaking down stereotypes about Orthodox Jews, where he was recognised as an “Orthodox Jewish all-star.” He told Insider that keeping kosher has led to some amusing misunderstandings when restaurants try to accommodate his dietary restrictions.

“I’ve had [kosher] airline food brought in the fanciest restaurants in the world,” he said. “I’ve had people serve complete traif [non-kosher] and say, ‘This is kosher.’ I’ve had people bring ham and say, ‘This is kosher.’ I’ve had it all.”
