The mission isn't even historically Hispanic. So it doesn't have the flavor as might the Mexican neighborhoods in san jose. The mission has been one of the historical destination neighborhoods for new immigrants who settle in SF. So the mission does not have a stereotypical ethnic look and feel.
The one thing can be said about the mission is that along with old Chinatown and excelsior they are the immigrant neighborhoods, but the characteristics of the immigrants to these neighborhoods have changed over time and only old Chinatown has held on to its ethnic look and feel, but looking at it through that lens is unhelpful. If we look at Beijing of today, it has not retained the look of the hutongs. Cities change. That said, The new immigrants to these neighborhoods are now not foreign but urban domestic.
