Andale Taqueria started in Palo Alto, I am pretty sure, but now has SF and Los Gatos stores as well. Due to all the security restrictions (e.g., probably no butcher knives allowed to the chefs inside security, if there are chefs), I see that a lot of the good stuff on the menu elsewhere isn't on the menu in the G concourse, but it certainly is a true local mini-chain and well worth considering if the airport place is even half as good as their other restaurants, especially compared with what is normally available on concourses!
