Prince Harry who is currently busy with Invictus Games, has rang in his 39th birthday on September 15, and enjoyed his pre-birthday celebrations in full swing with Meghan in a traditional German bar last night.

The Duke and Duchess of Sussex had a night out with friends in Dusseldorf as the Invictus Games came to a conclusion.

The bar staff warmly described the royals as 'charming' and were appreciative of the generous gratuity they received, all while relishing generous servings of red cabbage and mashed potatoes by having a bratwurst sausage along with six beers.

As Harry indulged in six half-pints in celebration, Meghan opted for a more modest single drink.

Guests at the Im Goldenen Kessel restaurant and bar were kindly requested to refrain from taking photographs, but they enthusiastically observed Prince Harry, who appeared to be in high spirits, sharing laughter and jests as the delectable dishes were served at his table.

Furthermore, his delight was palpable when a birthday cake made its grand entrance to conclude the meal.

Harry and Meghan graciously took photos alongside Thea Ungermann, the restaurant's owner, and Frank Wackers, the veteran head waiter with an impressive 38-year tenure at the establishment.

Ungermann informed MailOnline, “Harry was a lovely man and was having a very jolly time. Meghan was lovely.”

Moreover, Wackers informed the publication that Harry enjoyed six petite beers, which were approximately half a pint in size, a departure from the typically larger liter-sized beers served by most German breweries.
