I went to Monte Alban (11927 Santa Monica Blvd, (310) 444-7736), a Oaxacan place in West LA. It has been recommended here, and I thought it was quite good. I ordered a barbacoa taco and the coloradito chicken. The chips were superior and the salsa was good but not exceptional. The barbacoa taco was actually more in the burrito range. It was quite good but again not exceptional. The coloradito, though, was excellent with a deep red color and a vivid, aromatic taste. The chicken was a little dry but basically fine. It came with white rice that was fine as well.
I also ordered something called a clayuda, which I supposed from the menu was something like a big tortilla. In fact it is an 11"-diameter hard cracker, depressed in the middle, that's really meant to pile food on rather than to eat straight. The waiter saw that I'd only eaten a small piece of it and guessed correctly that it wasn't what I had expected. It sounded like this happens a lot, and she took the $1 for it off my bill.
In any case it's someplace I'd go back to.
