Kim, 38, was in town to celebrate Lala's 36th birthday and the group chowed down on a variety of treats at a cafe.
"Oreo shake! We're also going to have fried Twinkies, fried Twix, fried Reese's, were going in," Kim said in a video she posted to Instagram on Tuesday, June 25.
The Keeping Up with the Kardashians star also took a beignet for the road and gobbled it down while riding in the car to their next destination.
Kim launched her new shapewear line called Kimono Solutionwear earlier in the day but was quickly slammed by fans for only using skinny models to promote the collection.
The KKW Beauty founder heard the criticism and posted additional promo shots that included curvier models.
The mother of four recently embarked on a plant-based diet and frequently shares photos of her healthy meals, which include avocado toast, zucchini noodles, and other vegan creations, on social media.
