The Pacific Wharf in California Adventure is based on Monterey's Cannery Row area, supposedly especially as depicted in John Steinbeck's novels. Has anyone else read Cannery Row? I don't think anything Disney developed could quite be the same as that book. Disney doesn't normally do gritty like that.
Anyway. The wharf does resemble San Francisco's Fisherman's Wharf. I do like this area of the park for two reasons: the food and the textures and rust on all the buildings.
