So, I'm still slowly exploring the taqueria scene in my neck of the woods (just tried huaraches yesterday, a very pleasant revelation), and I have a question about the soups I often see patrons eating. Of the two acclaimed taquerias I've visited so far, one serves soup though it's not on the menu and the other features soup on its menu board, listed with the same meat options as its tacos, gorditas, etc. Unfortunately, there is too much of a language gap between the servers and me to ascertain what kind of soup these places are serving. So my question is, is there more or less a "standard" soup or soup base served at taquerias in the States? Or does it vary widely, and you just don't know until you take the plunge? Thanks in advance for furthering my taqueria education.
