He is a regular at a certain private members' club in London so it seemed like the perfect place for Prince Harry to host a dinner for a select few.
And it also gave him a night away from girlfriend Cressida Bonas as he joined some of the lads - and a couple of female friends - for a quiet meal.
The Prince, 29, was snapped leaving the Arts Club in Mayfair last night and heading for a car flanked by his security after the little bash at the club.

A source told EntertainmentWise that the dinner was just a "private little get together" for Harry and some of his rugby friends, James Haskell being one of them.
Lizzie Cundy and Made In Chelsea star Mark Francis Vandelli also attended.
Cressida was believed to be at home, maybe glad of the chance to have some me-time?
But our source said as soon as Harry left the bash he was headed off to see his leading lady.
They said: "Last night was lovely, but it was just a private little get together at the Arts Club, it wasn't for charity or anything like that.
"Cressida wasn't there but a lot of his rugby friends were as well as a few others, it was just a quiet little night."

And what did the Prince serve his guests? White wine, chicken and chips!
We all know Harry has been known to let his hair down from time to time but maybe as it was a Monday night, it was always going to be a subdued affair.
Harry recently hosted another private dinner, which took place at St James's Palace last week, but this time it was to praise and raise a few glasses to the Walking With The Wounded charity, members of which he trekked with to the South Pole at Christmas.
But although reports at the time suggested Cressida had been asked to co-host the bash with him, she didn't actually attend the bash, suggesting the couple are not yet ready to make their romance official.
