Although Zac Efron has been hitting the Hollywood scene solo lately, he and Vanessa Hudgens are still very much on. Here's the proof: Zac went to visit Vanessa in Vancouver this weekend, where the Disney duo hosted a dinner party together. How very grown-up!

V called Joe Fortes' Seafood and Chop House herself to make reservations for 16 people. "It was a party for her Sucker Punch castmates and her makeup artists," a source tells E! News of the occasion.

Jena Malone and Carla Gugino were among the guests who dined on family-style seafood platters.

But let's get to the details you really care about. How were Zac and Vanessa interacting?

"They were really cute and cuddly," the restaurant source tells us of the wholesome twosome. "Zac was rubbing her back throughout the evening."And now that Zac's legal, he picked his cocktail of choice: Grey Goose Greyhounds. The actor reportedly had "a bunch" during dinner.

Z and V stayed until the restaurant's closing. "They paid for dinner themselves and were great tippers," says the insider. The group then piled into a white stretch limo to head home. Vanessa must have known everyone would enjoy themselves since this isn't their first visit to the Vancouver restaurant. "One time, they came in and played the piano together and sang Disney songs," says the source. Awww, that's actually kind of cute. Carry on, kids!
