Diana's secret dinner dates with dishy doc; Candlelit four-hour meal for two.
Di was said to be "glowing with happiness" as she and Punjabi heart surgeon Hasnat Khan were spotted on TWO occasions enjoying candlelit meals.
But the doctor has become a victim of jealousy over the friendship. Mail has been opened and he asked BT to change his ex-directory phone number after being plagued by "nuisance'' calls morning, noon and night.
The Princess - once at the centre of phone pest allegations herself after men friends were deluged with calls - met Mr Khan at a West London hospital when a pal's husband had an operation.
Since then, self-styled "Queen of Hearts" Di has watched the surgeon carry out heart ops and the couple talk on the phone several times a week.
But the Sunday Mirror can today reveal that the Princess has also been driving 95 miles to Stratford-upon-Avon, Warwickshire, for discreet meetings with Mr Khan, well away from the lenses of the London papparazzi.
The dashing doctor - senior registrar to world-famous transplant pioneer Sir Magdi Yacoub - has a house just 10 minutes' walk from the unprepossessing Greek Connection restaurant. Diners stared as the couple strolled in on two busy Friday nights without any prior bookings.
It is a far cry from the upmarket London restaurants, such as San Lorenzo, which Diana normally frequents where lunch meals can run into hundreds of pounds.
Dinner at the Greek Connection costs no more than pounds 30, including wine, for two. They sat at a table in a quiet corner and stayed four-and-a-half hours, leaving together at around midnight.
Diana, who wore a grey jacket, white T-shirt and long black skirt, ordered moussaka for her main course - price pounds 6.25 - while Mr Khan had a vegetarian dish. Both had fresh strawberries for dessert.
Restaurant boss Lazarus Seferidis said: "The staff were as amazed as the customers when Diana walked in. We had no idea she was coming."Diana looked totally unruffled. She even smiled as she walked in.
"It looked as if she was enjoying all the attention. She and the man looked to be enjoying each other's company.
"At times they seemed quite intense and very wrapped up in each other's conversation.
"Neither of them were extravagant in what they ate. They seemed more interested in each other than the food.
"Not many people spend over four hours eating a meal, so it was quite obvious they were enjoying themselves.
"Diana was very friendly to me and all my staff. She complimented me on the food and said she had enjoyed the evening."
Two weeks later the Princess and Mr Khan went back to the Greek Connection. Again, they spent over four hours there. She was asked several times for her autograph and happily obliged, even signing one woman's napkin. There was no sign of a bodyguard.
Diana has also twice visited another Stratford restaurant, The Italian Job.
Its manager confirmed that the Princess had eaten at his establishment - which is almost opposite the Greek Connection - but he refused to give details of her visits.
All his staff have been strictly warned not to talk to the Press about the royal visits.
The Princess has seen Mr Khan during frequent visits to the Royal Brompton Hospital, in West London, where he works.
And the handsome surgeon - described by friends as an Omar Sharif lookalike - has also visited the Princess at her Kensington Palace home.
Mr Khan moved to London from Sydney in 1991 after kidnappers murdered the top heart specialist he worked with, Dr Victor Chang.
The surgeon also has his London home in a house just 50 yards from the hospital where Di makes some of her famous late night "angel of mercy" trips to visit sick and dying patients.
A hospital insider said: "Their friendship is becoming the talk of the hospital. They speak on the phone regularly and they meet often."
