I'll confess, I like starbuck's reliability. But I gave Mojo's much of my life (and money) during college. The coffee is above average, though I tended to stick mostly with the Iced Mojo which I've never been able to completely duplicate.
They have both indoor and outside seating (preferable because of the smoking crowd that the place tends to draw). Inside is pretty neat though-- they have rotating original art. The baristas (is that just a starbucks term?) are nice and original, and never seemed to mock my lack of originality (compared to the crowd, i was a preppie i suppose).
I could sit outside Mojo's (with certain boys that weren't my boyfriend) for hours sipping my coffee, ignoring both my bladder and certain boys that WERE my boyfriend. Just a great place to pass time
