The room shown is the conference room for the Justices. It's where they meet when it's only the nine of them (no clerks or other staff). Sounding each other out for votes, assigning cases, deciding whether or not to decide (that is, the Court doesn't accept a case to be heard unless four Justices or more vote it should be heard)... that sort of thing.
By tradition, the least senior Justice is who makes the coffee. Because it's been 11 years since Breyer came to the Court, that means he's been making the coffee the entire time.
