Should local cafes and bakeries be required to provide free Wi-Fi for their customers?

Baker Chad Robertson will open his new 7,500-square-foot facility, Altbau, in San Francisco on October 29, 2026. The space will accommodate 150 guests and aims to serve neighborhood commuter traffic during evening hours.

Why it matters

By milling its own einkorn, the bakery intends to lower costs associated with the expensive grain while providing fresh ingredients. The venue also plans to foster community through various workshops and late-night operations.

The 7,500-square-foot venue is equipped with a six-burner stove, a pizza oven, and a Rational combi oven. Additionally, a second-floor stone mill will process grains for daily use.

The players

Chad Robertson

He is a renowned baker known for his work in the artisan bread movement and the expansion of his bakery operations.

The details

The facility is accessed via a long, dedicated alleyway and features a glass-and-tile pastry counter alongside a coffee station. Operating without Wi-Fi, the bakery holds a liquor license and plans to host events ranging from floral-arranging classes to listening sessions.

November 7, 2026: Altbau hosts its first pop-up with Atelier September.
November 8, 2026: The second day of the pop-up event takes place.

Culture Shift

Altbau reflects the broader movement among artisan bakeries to prioritize in-house grain processing to manage costs and quality. This shift away from pre-milled flour highlights a growing emphasis on farm-to-table supply chain control within modern urban bakeries.

Commuters can expect evening service options, as the bakery plans to extend hours to 10 p.m. on weekdays and 2 a.m. on weekends. Customers should note the lack of on-site Wi-Fi, suggesting the space is designed for social interaction rather than remote work.

The takeaway

Visitors planning to frequent the bakery should prepare for a social atmosphere centered around food and community workshops. The use of an on-site grain mill suggests a commitment to high-quality, freshly processed ingredients in every loaf.
