If you're dressing up for a night on the town in Cambridge, you'd best put on your thinking cap. Home to Harvard and MIT, its citizens are the most educated on our list. You'll find year-round lectures, classes and exhibits at the local schools.
But there are still plenty of ways to unwind while exercising your brain. Learn wine-pairing at the Cambridge Center for Adult Education. Take a cocktail class at the ArtBar. Meet a filmmaker at the Brattle Theater. Or take the Classic Hahvahd Tour, an offbeat, student-led expedition through the nation's most famous school.
