Oysters Hawaii

Oysters Hawaii is Hawaii’s first and only mobile oyster bar, and the business strives to increase the accessibility of oysters to locals.

“We provide a one-of-a-kind experience featuring our mobile oyster chefs shucking fresh oysters sourced from local distributors,” explains business co-owner Julie Chu Fieman. “We offer an array of housemade condiments made with premium local ingredients, including a smoked gluten-free shoyu, ponzu sauce, Hawaiian chile pepper water and our classic champagne mignonette.”

Oysters Hawaii’s service window is typically one-to-two hours long. The biz values giving back to the community and taking care of the land — upon completion of services, the business’s used oyster shells are compiled into compost, where they are later donated to local farms as fertilizer.
