So, my boss, his secretary and myself found ourselves about a block from the Northgate grocery store and in need of a place for a quick lunch today. We headed over to Northgate and tried the taqueria.
I'm not sure what my boss had, but his secretary - always an adventursome eater - had two tacos, one of chicharrones in salsa verde and the other of buche (mostly pork stomach). She said the bouche was pretty good but the chicharrones only so-so. I had two tacos as well, one of chorizo (which also included diced potato) and one of carnitas. The chorizo taco was the better of the two and is actually one of the better ones I've had in S.D. The carnitas were tender but not terribly flavorful.
Tacos are $1.50 each and each comes with two very decent corn tortillas, are generously filled with your choice of about 6 or 8 fillings and then topped with the usual chopped onion, cilantro, salsa and lime. Other fillings included azada, cabeza, lengua, barbacoa, chicharrones in salsa rojo (in addition to the verde) and a couple of guisado type options.
My boss did not have a beverage. His secretary had a horchata which was utterly horrid. It was clearly from some type of mix as it was so sweet you literally could not drink it, and tasted of nothing but artifical flavor. I can honestly say it is the worst horchata I think I've ever had. I had an agua fresca de guanabana, which was much better, though a little weak on the flavor. But I'm not sure it's guanabana season and I've never really seen them in S.D. I tried it mostly because it *IS* my favorite agua fresca in Mexico and this was the first time I've seen it in San Diego.
So, on the hot food at Northgate I'd say it's hit and miss as the chorizo and buche tacos were pretty good, but the carnitas and chicharrones lacking. Best bet would be to try different things to find what you like best.
I also picked up a Pan de Muertos which is absolutely divine. There is nothing iffy about this version. While I have some reservations about recommending the taqueria at Northgate I have no reservations whatsoever about recommending the Pan de Muertos, it's pretty solid.
