So imagine if you went to a store, but instead of a person helping you, there was a big shiny machine that you could use to buy stuff. That's kind of like what the Beverly Hills Caviar Automated Boutique is.
Except instead of toys or clothes, this machine sells very fancy and expensive fish eggs called caviar. Caviar is usually eaten by really rich and fancy people, like movie stars or princes and princesses.
But now, if you're rich or just really want to try some fancy food, you can use the Beverly Hills Caviar Automated Boutique to buy some caviar. All you have to do is put your money in, pick which type of caviar you want, and then a little door will open up so you can take your caviar.
It's kind of like a big vending machine that sells really fancy fish eggs instead of candy or chips. But you still have to be careful not to spend all your money at once!
