I've always had great red sauce at The Shed. Busy and the bar can be pretty raucous. Wonderful $$$($) food at Geronimo. Fajitas at the cart on SW corner of Plaza. Roasted corn, NW corner of Plaza, across the street. Drinks at The Dragon Room, by The Pink Adobe. Smith Gallery, smaller than it used to be, still has some great images they'd be happy to sell you. Pasqual's. Go early to beat the line or just late enough to get the lunch menu for breakfast. Chicken enchiladas with mole.
The Sanctuario in Chimayo, 30 minutes north of SF, if that's your thing. The heat and dust and The Vigil Store; things almost haven't changed since the 1940s and the drive out is lovely. Couple of rug shops to the north of the enclave, next to the highway (76?) west to Espanola or east, uphill to high country (unpaved, then paved) and eventually into Taos. Bandalier has native cave dwellings and you can climb traditional ladders where a fall would be quite serious. Like, a genuine experience, not Disneyland.
I use almost nothing but 28 and 50 there but still bring a 21 and a 90. SF and environs is at 7,000+- feet and the light is everything you've heard about. I shoot B&W and cannot speak of colors. Early and late for the sweet raking light.
A lovely scruffy town, The City Different. Can be infuriating too.
My favorite. Enjoy.
