National Acts: Live Music at the Palladium! 
The Palladium, just a mile and half down Main Street from Clark, plays host to some of the country's best music acts. A huge bonus for any music fan.
Worcester has some great restaurants in the area. My personal favorite is Mezcal, a Mexican place on Shrewsbury St. There's a pretty good restaurant just a block from campus called Peppercorn's, and plenty of pizza, Chinese and Vietnamese places too. I interviewed some Clarkies this summer and in one of the videos, seen here on YouTube, they discuss their favorite places to eat.
