The book is a juvenile chapter book from the ’70s or ’80s. Called something like _Best Friends_. It’s about a girl who loses her best friend to another girl. I remember that she eats Chinese food with a new friend at the friend’s restaurant. She also participates in a puppet show from Alice in Wonderland and she is the Red Queen. The former best friend comes crawling back after a fight with the new girl but she realizes that she likes having lots of friends vs. exclusive to one best friend.
