If you're like me, you've driven past the little market at Cully and Wygant without a second glance, assuming it's the kind of place that sells lottery tickets, international phone cards, and beer. That was a mistake I made for 3 years, and then I checked inside.
La Oaxaqueña is a serious little Mexican market. Specifically, *Southern* Mexico, Oaxaca. The main thing you'll know this region of Mexico for is Mole sauce, and indeed they have prepared mole sauces in a variety of formats, including jars, spice mixes, and dehydrated paste blocks. I recommend the last, mostly because it includes a local brand.
Other things available at this market include prepared masa for making your own tortillas, all the different Mexican spices there are, high-quality locally made tortillas and chips (4 Hermanas and 3 Hermanos), and lots of Latin canned and dried ingredients -- mainly Mexican but even a few other items like Cuban bitter orange sauce. The one thing they're really weak on, though, is produce; you'll want to pop by the nearby Albertsons for that. And no beer, after all.
Also, they have pinatas.
