Unfortunately, there is no surefire way to see someone else's Snapchat Best Friends. However, there are a few methods that you can try in order to get a general idea of who someone's best friends are on the app. One method is to look at the person's Snapchat score. If they have a high Snapchat score, it is likely that they have added a lot of people as their best friends. Another method is to look at the person's Snapchat history. If they regularly communicate with certain people on the app, it is likely that those people are their best friends. Finally, you can try asking the person directly who their best friends are on Snapchat.
