They just opened an Amazon Go store in LA (Woodland Hills) at the beginning of the year. From my unscientific sample of personal visits it seems to be getting decent traffic, is well run, and is a much nicer place to quickly grab something on a walk over a gas station or a market that only takes cash.

For whatever reason there's also a Whole Foods and an Amazon Fresh near by as well. Woodland Hills is well stocked with Amazon retail!
