Chain, the fast-food concept from "The Office" star B.J. Novak, will open its first long-term residency at the Westfield Topanga mall in Canoga Park next month, [Eater is reporting](https://la.eater.com/).

Beginning Sept. 2 at Topanga Social, the mall's sprawling food hall, the residency will feature dishes from four celebrated chefs: Roy Choi, Mason Hereford, Mei Lin and Calvin Eng. Chain will also partner with General Mills on a menu of snacks and desserts built around the brand's cereals.

Launched as a parking-lot pop-up [reimagining nostalgic fast-food and chain restaurant favorites](https://www.eater.com/24152229/chain-pop-up-hollywood-celebrities-taco-bell-pizza), Chain has since grown into a full-fledged lifestyle brand, with a [permanent space in Virgil Village](https://la.eater.com/2024/1/17/24037032/chain-restaurant-bj-novak-chef-tim-hollingsworths-fast-food-pop-up-opening) hosting pop-ups and collaborations.

The residency comes amidst a wholesale reboot of Topanga Social. Opened to considerable fanfare in 2023, the food hall had [lost most of its vendors](https://ktla.com/news/local-news/topanga-social-food-hall-collapse/) by early May. In June, Westfield announced an all-new lineup of food stalls and entertainment, set to open on a rolling basis, including Umari Hand Roll Bar, Ozzy's Apizza and Pompadour Café.

The new vendors join another anticipated arrival at the mall: Din Tai Fung, which is [slated to open a Westfield Topanga location in 2027](https://la.eater.com/coming-attractions/299083/din-tai-fung-opening-westfield-topanga-canoga-park-2027).
