Williamson launched her Brentwood eatery Zax as Executive Chef and began her signature California-inspired cuisine. She then got married to Nick and the two opened their first independent venture together a couple of years later, Amuse Café in Venice.
The couple debuted their unique, beloved four-in-one concept, Playa Provisions, featuring a grab-and-go marketplace, King Beach in 2014. However, their restaurant Hudson House in Redondo Beach, The Tripel in Playa del Rey, and Da Kikokiko in Playa Vista were closed in 2020 due to the COVID-19 pandemic.
