Ramani's fashion designer daughter Malini, who is also a key witness in the case, accompanied her.
The meeting comes after the city police issued look-out notices against all nine accused and witnesses in the case to prevent them from leaving the country without prior permission.
It was in Ramani's restaurant Tamarind Court in South Delhi that Jessica, a fashion model, was shot dead on the night of April 29-30, 1999.
"I have nothing to hide," Ramani, apparently unhappy with the issuance of look-out notice against her, told PTI before the meeting.
"I have been in India ever since the incident happened and I have always cooperated with the police," she said.
