Sage Regenerative Kitchen & Brewery, a former US vegan restaurant chain, made the decision to close all its Southern California locations after adding meat to the menu and losing customers. The co-owners made the ill-fated decision to transition to a menu based on "regenerative agriculture," including animal-based products, which disappointed the L.A. vegan community. The addition of animal products led to protests from animal rights activists and a negative reaction from former customers, causing the restaurant to lose its vegan customer base.

The closure of Sage Regenerative Kitchen & Brewery serves as a lesson for other plant-based restaurants, highlighting that adding animal products to the menu and falling for the deception of "regenerative animal agriculture" will lead to losing vegan customers who know better. This unfortunate outcome emphasizes the importance of sticking to a vegan menu in order to maintain the loyalty of the vegan community and ensure the success of the business.
