Had lunch at Guelaguetza (the WLA one) today. I was there by myself, so I only ordered two dishes: 1) Tacos de tasajo, and 2) Mole verde with pork.
Although I am a bit spoiled (by virtue of having lived in Mexico for over two decades) when it comes to Mexican food, I must say I was a bit disappointed.
The tasajo tacos were OK, but the tasajo was a bit dry, and without the distinctive flavor it usually has in Mexico/Oaxaca.
The mole verde I liked less. The sauce was rather strange. Way too gloppy (is this a word?), almost gooey. Not to mention the color - radioactive dark green. (In contrast to the lighter color of, say, a pipian-like mole verde) More importantly, it lacked the depth and complexity that a mole should have. Felt a bit like what Chinese folks must feel when they eat "Chinese" food (i.e. sweet n sour) in sub-par restaurants in the US.
I'd be ready to give Guelaguetza another try though. Several dishes sounded great (just like what you'd get in Mexico, i.e. at Mi Bella Lula, a great Oaxacan joint in Mexico City; from enfrijoladas to tlayudas to chapulines to...), so I may give it another try. Not sure what the local hounds think of Guelaguetza though.
Still, the two dishes I had today were rather underwhelming.
I will try at some point Monte Alban, which I have noticed gets stellar reviews from you folks.
