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.
