I spent time at the Walnut Creek one -- it was a good execution of a kind of obvious idea. It was weird that they shut them down. That said -- smaller versions of the same format in airports/commute-centers would be great.
I asked a clerk at the Pleasant Hill store about that closure; it was due to rent increases. Figures, considering the location in downtown Walnut Creek. Sure was a lovely store, though. Fairfield and Reno still have big stores if you're ever in the area.
My upper comment was about the Amazon store they had in WC… but: B&N re-opened in Walnut Creek just below Ruth’s Chris. More like the Concord format.
Amazon is mostly an online company, they're not great at managing storefronts. They also really over-expanded their warehouses and physical presences which hemorrhaged cash (mostly led by Dave Clark who later stepped down as retail CEO) which was quickly shut down by Jassy who is more focused on AWS/cloud than retail presence.
