What We Missed While Watching the Movie "21"?

Essentially, half of the movie is "location fan service" for Harvard graduates. Since most of the locations shown outside of Las Vegas are iconic places around the university. They are all located in the center of Boston (yes, that's where Harvard is). And each spot is already steeped in legends—famous people have sat and gathered there, planned famous projects, and so on. For those who don't know, it's just people gathering in a cafe to discuss a game strategy, but for Harvard graduates, it's a powerful layer of nostalgia!
