I was in Denver over the weekend and went to Los Carboncitos, El Coyotito, and Taqueria Patcuarao.
First time I'd been to Los Carboncitos(went to the one at Pecos & 38th), and I really enjoyed the food there. I had huarache al pastor and my wife had a steak & chorizo huarache, both very good. Nice variation in the 4 very good condiment salsas provided. No chips here. Best food of the weekend was frijoles charros; I would designate this as not to be missed. Sopa azteca was okay but not something I'd order again. The refried beans were also just okay. Looking forward to trying out their other huaraches and getting my own bowl of frijoles charros when I return. Service was matter of fact but I didn't feel any of the unwelcoming vibe(from employees or patrons) that I've seen mentioned.
Also my first time to El Coyotito. Just one salsa offered there, and it was good. Bag chips. Guacamole was very good. I had carnitas tacos and abobada tacos. Preferred the adobada. I ordered spicy when asked for a preference, but it wasn't hot. I like cilantro and there was a lot of it on my tacos, might be too much for some people. Better refrieds than Los Carboncitos. My wife got a carnitas plate which she thought was okay, nothing to cheer about which was pretty much my opinion of my carnitas tacos from El Coyotito.
Second time to Taqueria Patzcuaro. Good salsa, good guacamole, good chips. I split carnitas and tacos albanil with my wife. Better carnitas there than at El Coyotito. The tacos albanil(grilled steak, potatoes, and jalapenos) were a nice change from what I usually get when I order tacos. Still think the refrieds there are some of the better ones I've had in Denver. Service had a familiar tone similar to that I've gotten at Jack n Grill which I like.
