A look inside San Francisco's new Amazon Go store

This Amazon Go store opened Tuesday in downtown San Francisco, at 300 California Street.

Everyone who enters must first download the Amazon Go app and scan themselves in at a turnstile.

Inside the Amazon Go app, a unique QR code appears for you.

Scan the QR code, and you can start shopping.

The store includes grab-and-go salads, chips, condiments and sandwiches.

Just grab a sandwich from the shelf and the item is added to your virtual shopping cart. If you put the item back, it gets removed from the cart. Once you walk out of the store, whatever goods you're still holding onto will be charged to your Amazon account.

Overhead, an array of cameras watch the products on the shelves to see what you pick up. Amazon says it uses a handful of technologies, including computer vision, sensor fusion, and deep learning, to make the store work.

In addition to fresh prepared foods, the store offers daily-staple groceries you might want to pick up on your way home from work.

Though Amazon got rid of cashiers at Amazon Go stores, it says it still employs about as many people as a regular convenience store. The company says it's able to redeploy workers to do other things, like stocking shelves, cleaning, and preparing foods.

Chicken banh mi and other sandwiches.

Take your pick of sauces.

About half the store is fresh foods. The other half is more like your typical corner store, offering chips, drinks, candy, condiments and so on.

I can't decide between Phish Food and Colbert's Americone Dream.

Chocolate, of course.

Amazon Meal Kits are available in store as well.

Amazon tells me these souvenir Amazon Go store water bottles are very popular.

This sushi cost me $13.99, and was far, far more delicious than typical supermarket sushi. 

Branded mugs are a popular item in the Go stores, Amazon says.
