While little has been publicly announced about the project, the ownership group behind Neptune Sushi brings together several familiar names from San Diego's restaurant scene. According to a California Department of Alcoholic Beverage Control filing, the new restaurant will operate under Neptune North Park LLC, whose managing members include Dillon Berkabile and Tanner Berkabile. The filing also lists Michael Harrison as a member, along with Blues Restaurant LLC.
The partnership reunites Berkabile and Harrison, longtime collaborators whose portfolios have quietly expanded across San Diego over the past decade. Berkabile is perhaps best known as one of the founders of Bowlology, the health-focused fast-casual concept that helped popularize acai bowls and healthy dining throughout Southern California. He has since become involved in a growing collection of independent restaurant ventures, including Pacific Beach's popular all-day café Palmy's, which opened in 2021.
Harrison has likewise become one of San Diego's more active independent restaurateurs. A chef by training, he previously served as opening general manager and executive chef at Palmy's before partnering with Berkabile on Blue Whale, the all-day coastal café that debuted in La Jolla Village in 2023. More recently, Harrison launched The Barista Botanist, an organic café in Pacific Beach, while also operating catering company Munch and artisan dessert concept Killer Whale Creamery.
Although Neptune Sushi has yet to unveil its menu or design plans, the name suggests a modern Japanese concept that would continue the property's long-standing connection to Japanese cuisine while giving the space an entirely new identity.
The address carries significant history within North Park's dining scene. Most recently, the space housed Tajima North Park, one of the neighborhood's longtime ramen destinations. That restaurant quietly ceased operations earlier this year after serving diners for nearly ten years, marking the end of one of San Diego's original ramen brand's most recognizable locations.
Founded in 2001 by restaurateur Isamu "Sam" Morikizono, Tajima helped introduce authentic ramen to San Diego years before the city's Japanese dining boom accelerated. While the North Park location closed, Tajima continues operating several restaurants throughout San Diego County, including its recently opened Crown Point location.
Neptune Sushi represents another notable investment in North Park, where restaurant turnover has remained unusually active over the past several years as operators continue adapting to changing consumer habits, rising operating costs, and evolving neighborhood demographics. The ABC filing currently seeks an on-sale beer and wine license for Neptune Sushi, suggesting the restaurant intends to complement its menu with alcoholic beverage service.
Beyond the licensing documents, however, few details have been publicly released. It remains unknown whether Neptune Sushi will focus primarily on traditional sushi, contemporary Japanese cuisine, izakaya-style dining, or a broader coastal concept influenced by the backgrounds of its ownership team.
SanDiegoVille reached out to Dillon Berkabile seeking additional information regarding the concept, menu, timeline, and design plans but did not receive a substantive response prior to publication.
Neptune Sushi is planned for 3015 Adams Avenue in San Diego's North Park neighborhood. An official opening date has not yet been announced.
