Common questions
How does JRA decide which restaurants show as kosher?
By default JRA shows food places whose hechsher is on the cRc list of recommended agencies and was confirmed on that agency's own list in the last 7 days; a listing hides itself when that check gets older. Places under other hechshers are behind a checkbox, marked "ask your rav".
