I took your advice at ate here last night. I just always assumed OS was a tourist trap, which of course it is in many ways, but this place was great if not a bit pricey. The traditional margarita was good and strong and not too sweet, served on the rocks with hornitos, cointreu, etc. Delicious. Gauc was a little on the bland side, but fresh and not doused in sour creme. Complimentary salsa was sweet but a bit liquidy. I had the pork pibil, which is marinated overnight and then baked in a banana leaf. relaly tender and delicious. it came with black beans and rice. My fellow diner had the carne asada, which was tender, a bit salty but good! That came with pinto beans and rice. Didn't see the final check, but I think it was about $50 something total for 2 drinks, 2 entrees, and the guac. Not saying I would run back here right away, but if I had family in town who'd never been to Olvera Street or just need a moderate place to eat downtown near the metro, this might be it. Oh, and the building is historic. I think first brick building in LA. I was there at night but probably fun to watch all the shoppers in daytime from the patio.
