Amazon opened its first cashier-less Amazon Go store in San Francisco this week and it's located in the Financial District at 300 California Street.
The store is pretty much a modern corner store — complete with candy, frozen pizzas, and chips —along with some fresh pre-packaged lunch options.
Amazon's "Just Walk Out" technology worked seamlessly in our experience, though first-time shoppers can be a bit hesitant upon exiting.
Employees are excited about the future of the store and say that even without cashiers, there's plenty of work to be done.

On Tuesday, the cashier-less Amazon Go store opened in San Francisco.

Amazon Go is the company's vision for the future of shopping. The store uses cameras, sensors and other technology to track the goods you pick off the shelves and automatically charges it to your account when you walk out. No waiting in line.

Amazon opened its first Go store in its hometown of Seattle in 2016. There's one in Chicago. And now it's expanding to San Francisco.

We stopped by the new store at 300 California Street to grab a sandwich and see what Amazon's "Just Walk Out" shopping experience was like.

Here's what we found:

Amazon Go's first San Francisco store is located smack in the middle of the city's financial district — and, as luck would have it, just a few blocks from the Business Insider office.

The store, which is open from 7am to 9pm Monday through Friday, seems aimed at the office worker crowd; Busy, time-pressed desk-jockeys looking to gab a quick bite or a juice on their way in, or out, of the office. At 2,300 square feet, this Amazon Go store is cast in the mold of your average 7-11, rather than a supermarket, when it comes to size.

Before entering the store, customers were prompted to download the Amazon Go app, which created some congestion and confusion outside.

Employees we spoke to said that downloading the app had been the biggest pain point of the day.

People forget their passwords. Others frantically tried to get ahold of their spouses to log in to their accounts.

I failed the reCAPTCHA test twice but eventually got it downloaded.

Without the Amazon Go app, you are not able to get past the sensor gates to start shopping.

There's a QR code in the app. You flash the code on your phone's screen in front of the sensor, as with an electronic plane ticket, and voila — the gates open.
