The thread below got kind of long and hard to scroll down to, so I thought I'd start it here again.
This place, I agree, is definitely a winner. Jesse and I both had the beef faijitas and it was more like some of the best I've had in Tucson than anything ever sampled in SF. It came with homemade tortillas, refried beans (although I heard someone after us order black beans that were not on the posted menu), a simple salad with radish garnish, and a good Mexican rice with chunks of carrot and zucchini.
I also concur that the guacamole was one of the best versions ever -- more of an avocado, tomato, chile salad with the avocado in small dice rather than smashed and dressed with plenty of lime.
I can't wait to try the specials. There weren't any this evening, but the chef brought out to a friend (or maybe employee) just before we were leaving a plate where the main portion was a half chicken breast smothered in a cheese/habenaro sauce (the chef said when we asked). He says he's fine tuning it and it will go on the menu next week.
We also had a good, tart fruit drink that tasted between a jamaica and a fresh black currant drink. We also were given a taste of the orchata -- excellent and cinnamony if you like that sort of thing but too sweet for me personally.
The only question I have is what is a french guy (the owner or manager) doing with a Mexican taqueria (no matter how upscale) in San Francisco?!
The room is nice too, by the way, with an atrium in back and what looks to be a nice garden as well.
