Neptune Sushi Opens In San Diego's North Park With Handroll Bar And Locally Caught Seafood Focus

San Diego's North Park neighborhood has a new sushi destination as Neptune Sushi officially opens its doors, taking over the former Tajima ramen restaurant on Adams Avenue. The highly anticipated restaurant promises freshly prepared hand rolls, creative Japanese-inspired dishes and an emphasis on locally caught seafood, bringing a new coastal dining concept to one of the city's busiest neighborhood restaurant corridors.

Neptune announced its grand opening Sunday morning through its Instagram account, confirming that the restaurant is officially welcoming customers from 11am to 10pm. The business also confirmed in response to a customer's question that it is accepting walk-ins, making the opening accessible to diners eager to experience the new space without advance reservations.

The opening comes approximately four months after SanDiegoVille first reported that local restaurateurs Dillon Berkabile, Michael Harrison and Justice Horden were transforming the former Tajima North Park location into an ambitious new restaurant. At the time, the ownership group described a concept centered on modern temaki-style hand rolls, with broader influences from Asian and Latin American cuisines and San Diego's coastal food culture.

Now that vision is becoming a reality, with Neptune positioning locally sourced seafood as a defining element of its identity. The restaurant has promoted a commitment to locally caught fish, an approach that could distinguish it from conventional sushi establishments that depend heavily on imported seafood. SanDiegoVille has not independently verified whether all fish served at Neptune are locally caught or identified the commercial fishermen and suppliers involved in the restaurant's sourcing program.

The emphasis on local seafood also reflects a broader movement within San Diego's restaurant industry toward supporting the region's commercial fishing fleet. Local seafood advocates have highlighted restaurants including North Park's Mabel's Gone Fishing, Pacific Beach's The Fishery and Nico's Fish Market, and Ironside Fish & Oyster in Little Italy for their relationships with regional fishermen and use of locally available catch.

Neptune's kitchen is led by chef Taylor Preus, whom Berkabile previously described as an experienced sushi chef who has spent years developing his craft. The restaurant's original vision focused on temaki, the Japanese hand roll traditionally assembled with seasoned rice, seafood and other ingredients wrapped in crisp nori, usually prepared and served individually for immediate consumption.

However, the owners have emphasized that Neptune is intended to offer more than a conventional sushi bar. In an earlier interview, Berkabile explained that the concept evolved considerably during the restaurant's design and construction process, incorporating broader culinary influences while retaining hand rolls and modern sushi at its center.

"Our vision for Neptune is to create a space that invites unique interpretations and continual evolution within San Diego's already thriving culinary landscape," Berkabile previously told SanDiegoVille.

Rather than committing exclusively to traditional Japanese preparations, the ownership group has described an evolving menu drawing inspiration from Asia, Latin America and Southern California. The result is intended to be a restaurant where fresh ingredients and creativity guide the experience rather than adherence to one particular culinary tradition.

"If I had to give Neptune a singular identity, I couldn't, because we don't want to be confined to one," Berkabile explained in June. "Neptune is simply going to be a place where we serve what is delicious, fresh, and creative."

The restaurant's design has been another major focus of the project. Co-owner Justice Horden helped oversee much of the interior transformation, incorporating reclaimed San Diego wood, natural materials, custom-built furnishings and carefully sourced vintage pieces in an effort to create a distinctive, handcrafted environment.

Berkabile previously told SanDiegoVille that much of the space was either built specifically for Neptune or sourced secondhand, rather than purchased as conventional restaurant décor. The concept's namesake, Neptune, the mythological Roman god of the sea, also influenced the restaurant's visual identity and design.

The newly unveiled interior features dark, atmospheric finishes, sculptural hanging lights and natural textures, departing from the casual ramen-shop atmosphere that previously defined the address. The restaurant's opening announcement prominently features its maritime-inspired branding and the newly completed space.

The restaurant is also listed within the online portfolio of Blues Restaurant Group, a hospitality collection associated with several of the owners' other ventures. The group's website includes Neptune alongside Blue Whale in La Jolla, Barista Botanist in Pacific Beach, Killer Whale Creamery and Palmys.

The partnership behind Neptune brings together several operators with extensive ties to San Diego's restaurant industry. Berkabile was among the founders of Bowlology and has been involved in numerous hospitality ventures, including Pacific Beach's Palmys, which opened in 2021 inside a restored Craftsman cottage on Felspar Street.

Harrison previously served as opening general manager and executive chef at Palmys before partnering with Berkabile on Blue Whale, the coastal café that debuted in La Jolla Village in 2023. His additional projects include Barista Botanist, catering company Munch and artisan dessert business Killer Whale Creamery.

Neptune's arrival also marks a new chapter for a recognizable Adams Avenue restaurant space. The property previously housed Tajima North Park, part of one of San Diego's original modern ramen restaurant groups, which closed earlier this year after nearly a decade in the neighborhood.

Founded in 2001 by restaurateur Isamu "Sam" Morikizono, Tajima helped introduce Japanese ramen to a broader San Diego audience long before the region experienced its current proliferation of ramen restaurants. Although its North Park location closed, the brand continues operating elsewhere in San Diego County.

For Neptune, the transition from a longtime ramen restaurant to a contemporary handroll bar reflects the continued evolution of Adams Avenue's dining scene. The corridor has attracted an increasingly diverse collection of restaurants, cocktail bars and independently operated hospitality concepts, with neighborhood operators competing to offer experiences that distinguish themselves from the city's more conventional dining establishments.

The restaurant has not yet published a verified full menu and pricing information. Additional details about specific hand rolls, locally caught seafood selections, beverage offerings and ongoing operating hours are expected to become clearer as the business settles into regular service.

Neptune Sushi is now open at 3015 Adams Avenue in San Diego's North Park neighborhood. For more information, follow @eatneptune on Instagram.
