Asian-owned and women-owned per its Google Business listing, OB Sushiya operates from Suite 17 at 4967 Newport Avenue, anchoring mid-block on the corridor's sushi tier. The kitchen pairs sushi-bar rolls, sashimi, and nigiri with a hot-line of bento, udon, ramen, miso, and yakisoba — a sushi-plus-noodles hybrid that mirrors the Japanese crossover format at Harumama Ramen by Blue Ocean Sushi a few blocks north. Specialty rolls such as the Hercules and Cherry Blossom anchor the menu alongside an 18-piece Chef's Choice and the vegetarian Veggie-pillar platter. Beverage service leans Japanese — sake bottles, imported beer, and a short wine list — distinct from the spirits-and-cocktail focus at Tony's Martini Bar further up Newport Avenue. The most composed plate in the dining room is the Chef Choice 18-piece, a sashimi-grade nigiri-and-sashimi presentation that runs the bar's full daily fish rotation in one omakase-style service.
