The two went out for dinner at Soho House, not too far from Kensington Palace

Prince Harry and Meghan Markle are taking their romance out on the town!

The royal and his Suits star girlfriend of more than six months were photographed during a night out in London on Wednesday, following Harry’s solo morning visit with ambulance crews to support his ongoing mental health campaign. The couple had dinner at the Soho House before walking hand-in-hand on a crowded London sidewalk.

“They tried to keep as low-key as possible and were sitting in a small snug area of the restaurant,” an onlooker told The Sun, who obtained the photos. “But it wasn’t a private area and they were happy to be seen . . . they only had eyes for each other.”

This isn’t the first time they’ve been out and about in London together. Last December, they were spotted in the West End after taking in a performance of The Curious Incident of the Dog in the Night-Time together.

Just this week, Markle’s Suits costar, Patrick J. Adams, spoke about her relationship with Harry in an interview with Access Hollywood. He said that he was thrilled that Markle found someone “that she seems to really be into,” but admitted that they don’t talk about the relationship much.

“I’m super happy for her, I would love to do that thing a big brother gets to do where you get to actually meet the guy, and vet him a little bit, go through that process,” Adams joked. “What are his intentions?”

PEOPLE confirmed in October that Harry and Markle, had been seeing each other for three months.
