Bam Margera didn't lose his appetite after surrendering to police to face charges for allegedly assaulting his brother ... getting right back to normal life with his girlfriend and her kid.
TMZ obtained these photos of Bam breaking bread with his chick and her 8-year-old daughter Thursday afternoon in West Chester, PA ... only hours after turning himself into cops and a subsequent court appearance.
Folks who were there say Bam hit up a restaurant called Stove & Tap .
