Enjoying Strongbow cider, the actor, who arrived solo, appeared to be "having a good time and talking to people," the source says.

Funny seeing you here!
Zac Efron and Cheryl Burke crossed paths when they both stepped out at Bootsy Bellows in West Hollywood on Tuesday.
Although they were spotted hanging together at the club just a few weeks ago, the stars had two very different nights.
Sporting a blue button-down shirt, a black beanie and a bit of facial hair, Efron kept a low profile in the club's back VIP room.
"His table was very crowded but he always seemed to be at the back of the crowd so he could have some privacy," an onlooker tells PEOPLE.
Even though Efron seemed focused on a laid-back night with his friends, a female patron managed to catch his eye.
"At one point, he was flirting with a tall, thin blonde. He was definitely charming her," the source adds. "But he left the club alone when they closed at 2 a.m."
While Efron kept his evening low-key, Burke made a fashionably late entrance, arriving around 1:20 a.m.
Wearing a white Grecian-inspired dress, the Dancing with the Stars pro was upbeat as she chatted with her friend, promoter Allison Melnick before hitting the dance floor.
"She wasn't shy and busted out her dance moves to songs like Rihanna's 'Birthday [Cake.]' She was having fun," says a source.
