character, Edward, may remain a perpetual teenager – but the actor celebrated turning 23 on Wednesday.
The star was joined by several of his New Moon
castmates, including leading lady Kristen Stewart
, Ashley Greene and Jamie Campbell Bower at The Glowbal Grill and Satay Bar in Vancouver where they are filming.
Pattinson and his pals were treated to champagne cocktails in the the V.I.P. section of the restaurant. They ordered rounds of shooters and feasted on Kobe beef meatballs, lamb, steak, salads and roasted vegetables.
"Everyone enjoyed a hearty meal and had a good appetite," said a source. But it's wasn't just a cozy night with friends. Pattison's location was posted on Twitter, and soon hoards of fans descended on the restaurant trying to get pictures and autographs.
"There was a lot of buzz and energy in the restaurant," said the source. "Being in the same restaurant as Rob Pattinson for his birthday is great."
A fan told PEOPLE: "I was so happy to see Rob and help him celebrate his 23rd birthday. He took the time to meet us and take a picture with us, that was so cool."
After dinner, a platter of desserts was taken to the table where guests could choose between cheesecake, créme brulee, warm chocolate coffee cake and white chocolate mousse. Later, the group made their way to Afterglow, a small bar attached to the restaurant where they had drinks, talked and listened to music until close to 1 a.m.
