There is nothing kid friendly about this place. It is now full of overpriced restaurants and shops. I would stear clear of the Cannery and opt for Gherdelli square and the wharf. Pier 39 is just a few steps away. There is a bunch of candy shops near the cannery though, if you need some sweets.
The largest peach cannery in the world at the turn of the twentieth century, this three-story brick complex now holds dozens of smart shops and restaurants, with an olive-tree-shaded patio for dining and free entertainment. The cable car turnaround is 1⁄2 block away.
