Turning 23 years old on Wednesday, May 13, Robert Pattinson decided to celebrate his birthday alongside his "Twilight" co-stars and paretns. Robert was seen heading to Global Grill and Satay Bar in Vancouver, Canada at around 9 P.M.

"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

Also joining them to have dinner at the restaurant were Pattinson's dad and mom. "Robert's parents were all smiles," the source continued. "They were kind of quiet but very gracious and polite. You could easily see where Robert got his reserved demeanor from."

Some other "The Twilight Saga's New Moon" cast, including Jamie Campbell Bower and Ashley Greene, were also invited to come to the party. Finishing their dinner, all of them soon moved to Afterglow lounge, a small bar attached to the restaurant, where they drank, chatted, and listened to music until at around 1.00 A.M.
