and his fiancée Lauren Parsekian snuck away for some alone time at the Clift Hotel in San Francisco recently.
The couple arrived at the Redwood Room – the hotel's romantic bar – and spent about an hour relaxing, ordering up a cheese plate that featured a variety of gourmet cheeses.
"It was just the two of them, quietly playing cards. Maybe Gin Rummy," an onlooker tells PEOPLE. "They seemed relaxed and happy. They were having a mellow evening."
Even though Paul has starred in Breaking Bad
for five seasons (and won two Emmys!), the casually dressed pair went "unnoticed by fellow guests," the source adds. "They were in laid-back San Francisco style."
