After an hour-long sneak preview for the building's tenants and other insiders, the city's second Eatsa officially opened at noon today at 1 California St., delivering a more compact, app-driven version of the fast, healthy quinoa bowl concept.

The first Eatsa opened at 121 Spear St. in Rincon Center last August, in a 2,000-square-foot space that offers some seating. This new incarnation, which faces Davis Street near Market, is much smaller, with only 800 square feet. It includes a behind-the-scenes kitchen where the bowls are prepared, along with a sleek storefront featuring a wall of futuristic glass-front cubbies where orders appear as if by magic. (We asked how many employees are in the back, and were told it's proprietary information.)

Though this location does have a few touchscreens for orders, the company wants customers to rely more on its app, which lets diners order ahead from their phones. "We really think that is what people are most excited about," said Tim Young, who owns Eatsa with Scott Drummond.

At the Spear location, he added, "If you just watch the doors, people will walk in, walk to a cubby and walk out. It's a frictionless experience." Food is usually ready with three minutes.

This is ideal for the hordes of workers in the FiDi who have limited time for lunch. Jeff Weaver, who's been going to the Spear location, is one of them. "We get our food and take it back to our desks anyway, so it fits perfectly," he said. "It's a cool setup. It's usually very efficient and fast, the food is really good, it's healthy, and it's inexpensive relative to other options."

All bowls are $6.95 and have a base of quinoa, topped with various internationally inspired ingredients. Chef creations include the Chili Con Quinoa, No Worry Curry, Bento Bowl or The Mediterranean, but diners can customize their own bowls as well. All are high-protein and low-calorie.

Unlike the original location, there's no concierge and no seating, but the One California management has been working on renovating its building and adjacent privately owned public open space (POPOS), and Young tells us the plan is to have more integrated seating out there than before. The new Eatsa's hours are 11am–5pm, Monday–Friday.

Workers are busy renovating the One California POPOS.

Eatsa has already opened a location at the Westfield Topanga shopping mall in Southern California, and we're told the plan is to open more outposts both here in the Bay Area, as well as on the East Coast, later this year.

Update, 3/25: A company spokesperson told us she misspoke when she originally said there's no concierge at the 1 California St. location. There is, in fact, a concierge on site to assist if needed.
