In town filming his new movie Pain and Gain, Mark Wahlberg made some time for dinner Sunday night with a pal at Bianca at Delano in Miami Beach.

Dressed casually in a white shirt and shorts, the actor continued on his bulking-up regimen by indulging in a traditional Italian meal of pasta pomodoro and wine.

"Mark seemed very relaxed," an onlooker tells PEOPLE. "He and his guest seemed to be having friendly conversation. There were no signs of business talk."
