Rocio's Mole de los Dioses, a super charming restaurant just off the 5. We found ithe restaurant thanks to the handy internets, but then learned it's been voted as having the best tortillas in town by the LA Weekly and is known for the menu of a dozen or so various traditional moles. With a web address like moleofthegods.com, of course we had to try one of the dozen richly layered sauces available.
We opted for the dark, rich, chocolatey, spicy mole Oaxaqueno over special pork and chicken tamales ('twas the season, after all), and while the tamales themselves were decent, that mole was amazing. We loved the attention to detail and presentation, the fried plantains that came with it, and the extra very green tortillas we had to sop up more sauce. We were so pleased to find such a cheerful spot in the middle of all the auto parts shops and warehouses surrounding us, especially one with ice cold Bohemia and that serves an amuse bouche (in this case a shrimp broth with a dynamite house-made cracker). If you haven't been, go.
