On Wednesday night, Jersey Shore's Paul "Pauly D" DelVecchio and Vinny Guadagnino stopped into Artichoke Basille's Pizzeria & Bar in New York City for a late night snack.
"They came in and had pizza and drinks," an onlooker tells PEOPLE. "They were very friendly and hanging out with other customers."
"Vinny and Melanie Iglesias were sitting together for most of the time. She kept trying to get the group to leave but Pauly D was holding them back, socializing with the crowd, having a blast!" the source adds.
Food Network personality Anne Burrell also made an appearance that evening.
"She came in with a friend and ordered a meatball pram pie to go," the source adds.
