The new kid on Union Street is no stranger to Cow Hollow.
Her older sister debuted on the same block—in the same exact storefront—back in 2018, a sophisticated restaurant with a menu inspired by Nikkei (Japanese-Peruvian) traditions that had just enough time to become a neighborhood fixture before Covid rolled through town.

While the family—the restaurant group BXB Hospitality and owner John Park—regrouped in 2022, tapping into the maximalist party vibe rising at the pandemic’s tail end with SoMa’s 12th-floor tropical restaurant and cocktail bar Kaiyō Rooftop (701 3rd St.), the original Kaiyō on Union stayed vacant. The neighborhood just wasn’t ready for the return of the polished, higher-end beauty. Four years later, it still isn’t: The city has changed, restaurants have changed, we have changed.
Park felt confident that what Cow Hollow needed now was something more energetic, casual, and playful. A creative younger sister to the original Kaiyō, she’d be an extrovert that was many things to many people: a spot for a quick bite, a gathering place for friends, a lively spot for dinner and cocktails that stayed open late. And at the center of her menu, a simple handheld item that would be anything but basic.
Handroll bars are a relatively new concept in Nikkei cuisine, and Kaiyō’s is the first on the West Coast to give top billing to the hybrid food that is a taco, a sushi roll, and a Japanese-Peruvian specialty all in one.
Whereas the typical “hand roll” (temaki) contains little more than raw fish and sushi rice wrapped in seaweed, Kaiyō’s push the envelope. They don’t just do a hamachi hand roll; they do a Hamachi Ceviche hand roll with yellowtail, onion, kombu, leche de tigre, and cancha. They don’t just do a shrimp tempura hand roll; they do an Ebiten Acevichado hand roll with tempura shrimp, salmon, tuna, unagi, and rocoto aioli. They don’t stick solely to fish and seafood, either. The multicultural mashup extends to include hand rolls filled with Nikkei favorites like lomo saltado and shoestring potatoes; crab, causa, and quinoa; and roasted duck with cilantro rice.

Each night, the ingredients for a few of the hand rolls get a place of honor on the hand roll cart. It glides from table to table, giving diners the chance to watch their selections assembled up close. Chef de cuisine Kenji Sawada is captain of that particular ship on the night I visit, tucking generous chunks of leche-de-tigre-cured tuna and seared salmon into palm-sized sheets of nori right in front of my eyes.
While the Nikkei hand rolls are the stars of the show, my favorite, the uni-toro, is a sleeper from the “classic hand roll” menu. Though I’m not usually a big fan of uni, its form at Kaiyō beautifully balances the urchin’s salty brine with richly marbled otoro and the spice of freshly minced kizami wasabi.
Another of my favorites comes from the menu’s collection of mains. The scallop udon in mentaiko sauce is almost like a Japanese alfredo, a comforting nest of soft, chewy udon laid with seared Hokkaido scallops and bathed in creamy rocoto dashi. The bivalves, like all of the fish and seafood served at Kaiyō, are imported directly from Japan’s legendary markets.
The small bites, appetizers, and ceviches and tiraditos more than hold their own against the menu’s namesake handrolls, too. The miso butter corn, already a favorite in Kaiyō’s brief few weeks in action, lives up to the hype with ribs of yellow corn smothered in savory miso butter and togarashi. The ceviche de camarones made with ginger-pepper leche de tigre, choclo, and chiles hits all the right notes.

Cocktails are designed by BXB Hospitality’s beverage director, Danny Louie. Instead of novelty, his menu aims for approachability—recognizable recipes with tropical and Asian twists like the Katanka (made with gin, tomato, mango, black pepper, lime, and cilantro), a savory gem that hovers somewhere between Bloody Mary and beachy brightness. Zero-proof and matcha beverages, as well as sake and craft Japanese beer, are also on offer.
Kaiyō Handroll Bar’s aesthetic similarly fuses Latin America and Asia. Designed by Park rather than a traditional interior designer, the front patio has tropical Peruvian vibes with plenty of greenery. Through the door, though, a different dimension unfolds, one inspired by night markets in Osaka and the buzzing streets of Tokyo. From the ceiling hang a rainbow of bangasas (traditional Japanese umbrellas); on the walls, a splashy cityscape mural and neon accents (check out the custom Sailor Moon slurping ramen). The bathrooms, where black-and-white Japanese-style comics have been painted from floor to ceiling, haven’t been left out of the fun.
While Kaiyō Handroll Bar has both Japanese milk bread and miso caramel bread pudding and guava-infused crème brûlée on its dessert menu, nearly everyone in the restaurant opts to end their meal with one of two versions of matcha soft serve: The regular swirl with vanilla bean or the alcoholic version. The latter, which combines the matcha soft serve with rum, coconut, and passion fruit is neither dessert nor nightcap. Like Nikkei cuisine itself, it’s the best of both worlds.
