At Sunny Side Fungi, we believe mushrooms are more than food — they’re a connection to community, nature, and well-being. Based in Costa Mesa, we partner with trusted local farms to bring fresh, sustainably grown mushrooms straight to farmers markets and neighborhood restaurants.

Our mission is simple: make high-quality mushrooms accessible while supporting California’s local growers and artisans. From market baskets to chef’s tables, we celebrate the flavor, nutrition, and artistry of fungi — always Sunny Side up.
