While Franklin Street has always been amazing - there are some especcially good places to make sure you stop by.
Try Spanky's for brunch, the Varsity or Carolina for an afternoon flick, Cosmic Cantina for a extremely cheap and tasty burrito, Schoolkids for music you didn't even know you liked, and so much more.
Pros: choices for eats
Cons: parking - 2hr. max, $, clothing expensive
