Ones Cafe & Bakery Finally Opens on Alameda's Park Street With Ube Croissants

A family-run bakery known for turning croissants into wildly stuffed, only-on-Instagram creations has finally opened its doors on Alameda's Park Street. Ones Cafe & Bakery debuted its second location at 1926 Park St. in July, months later than originally planned, joining Alameda's tight-knit strip of independent coffee shops and bakeries with a menu built around Asian-inspired pastries and coffee drinks.

The bakery is run by Cyrus Zhang and his family, according to East Bay Times, with Zhang's mother reportedly trained in culinary work in Japan and now overseeing baking operations. The Alameda shop is Ones' second storefront, following the original at 3483 Castro Valley Blvd. in Castro Valley. That Castro Valley space has no indoor seating and depends on outdoor tables, a stark contrast to the new Park Street building, which offers a full indoor cafe layout plus a private outdoor courtyard, according to The Gourmez.

A Six-Month Wait for Permits

Ones had initially aimed to open in Alameda around January, but the launch stretched to July 1 largely because of county health permitting requirements tied to installing new refrigerated bakery display cases, per The Morning Bun's reporting. The delay meant the storefront sat in transition for months after its previous tenant, Coffee Cultures, closed on January 31. That shop was run by Alameda native Jason Michael Paul and had operated multiple Bay Area cafes before shifting its Alameda presence to a mobile cart, the same outlet's coverage notes.

Even the courtyard's mural has history: it was created by Alameda artist David Burke during Coffee Cultures' occupancy of the space, according to the same account. The Castro Valley flagship has its own layered past, too — that tiny storefront previously housed Pampas Café, an Argentine empanada shop that later relocated to Redwood Road, the same outlet reports.

What's on the Menu

Ones Cafe & Bakery built its following on social media through a signature stuffed half-moon croissant, offered in flavors like ube and strawberry, alongside laminated dough shaped into bowties, wheels, croffins, croffles, and even pastry onigiri, the same outlet's reporting shows. According to East Bay Times, the Alameda menu also includes a lemongrass-chicken croissant made with marinated chicken thighs, lemongrass, a Thai chili mix and pepper-jack cheese, topped with a pickle. Other savory options include a wagyu pastrami cup with parmesan, potato and mozzarella, an asparagus bacon danish layered with onion, black pepper, Philadelphia cream cheese and Swiss cheese, and a tuna-salad danish finished with thousand-island dressing.

On the drinks side, the shop serves ube lattes, orange lattes, and an iced-only sea-salt cheese latte, per East Bay Times. The bigger kitchen and counter setup in Alameda also let the owners expand beyond the Castro Valley lineup with exclusive additions like an ice cream croissant, coffee soft serve, and affogatos, according to The Oaklandside's coverage of the new location.

Filling a Gap on Park Street

The opening lands at a notable moment for Alameda's bakery scene. It follows the October 2025 closure of Feel Good Bakery, which had operated for more than 20 years across its Encinal Avenue and Alameda Marketplace locations before shutting down, as reported by SFGATE. Ones now sits within Park Street's broader commercial corridor, which includes nearby bakeries like Crispian Bakery and Dandelion Kaffe, per the Downtown Alameda Business Directory.

The arrival also fits a wider regional pattern of Asian-fusion bakery concepts expanding across the East Bay. Oakland-born Bake Sum opened a second location inside the Alameda Marketplace in May, building on recognition for blending French pastry techniques with flavors like ube, mochi and Spam musubi, according to Richmondside.

Limited Hours, High Demand

Prospective customers should plan around Ones' unpredictable schedule. The bakery is open Wednesday through Sunday starting at 8 a.m., but it frequently sells out and closes early, sometimes before mid-afternoon, due to high demand and limited daily production, per The Gourmez. That pattern has held at both the Castro Valley and Alameda locations since the newer shop opened, the outlet notes.
