Vegan Las Vegas!
The Hit and Run costars were also joined by Bell’s parents.
“They were having a great time and were laughing together,” an onlooker tells PEOPLE.
Bell and Shepard – who are vegan – both ordered the URTH burger, a house made vegan patty burger.
Bell paired her animal-free lunch with a side salad and water while Shepard snacked on waffle fries and a Diet Coke.
