Kriste Stewart let loose with pals on Friday night in Los Angeles.
Hitting up El Arco Iris restaurant for some Mexican food and fun, the former Twilight star was joined by a group of male and female friends, and they ordered a big bowl of chicken soup, a pitcher of the strawberry margarita and a pitcher of the house special margarita.
“Kristen and her friends did a tequila shot,” an onlooker tells PEOPLE. “The staff said that Kristen was super sweet and was very thankful and even took photos with them.”
Dressed casually in jeans and a white T-shirt, the actress wore her hair wavy and down and flashed a peace sign in a photo that was taken at the eatery.
