I'm going to take my mother to this when she comes into town for xmas.

"Javawalk is a two-hour walk in the city center. We start at Union Square and wind through Chinatown, Jackson Square and North Beach, the city's Italian district. While we cover the city's coffee roots (much more significant than Seattle's!) and coffeehouse culture (think beatnik), we also spend some time on San Francisco's history, interesting and arcane trivia and stories the Javagirl has collected from many years of living in the city. Truly, some things could only happen in SF! Javawalk also makes a couple of stops at North Beach cafes for a quick java jolt. Since cool weather prevails here, we need coffee year-round in the city by the Bay. Lucky us!"
