I tried out the pioneras at el rey. They are an unusal and highly filling plate of tacos, but actually similar to something I make at home for the kids. And much loved by them, lots of gooey cheese, bacon, flour tortilas.
They weren't all that much to my liking though- just am not a fan of the storebought standard flour tortilla
Yeah, I can see that. My SO doesn't care for the Pioneros either. I am also not a big flour tortilla fan, but in the case of pioneros, I think they work. I like the Pioneros for their junk food quality, in the same way I like sliders. Pork, ham bacon, cheese and grilled onions on flour tortillas, doesn't exactly spell haute cuisine (I do like the idea of grilled onions on tacos though).
The first couple of times I ate the Pioneros at El Rey, I swore the tortillas were either homemade or a very good commercial version. The last time I ordered them, I saw them open a package of those tortillas in the clear and red package that are made on 26th st. I can't remember the name. The amount of cheese on the tacos also seems to vary. I like it when they go a little lighter on the cheese.
Anyhow, the carnitas are good at el rey (smokey) and so is the goat barbacoa. The al Pastor is pretty good and the tacos de Lomo pleasantly surprised me also (I expected it to be tough). The horchata is so-so, and the liquados are awful. Stay away from the Costillas de Res. They are cooked over coals, but have the texture of leather. I am also not a big fan of their salsa.
Aside from the kiddy tacos and the goat, I think there are better options in the vicinity than El Rey (e.g. Cuetzala). Plus, the restaurant is way too brightly lit. But they do great business, much better than nearby venues. They must be doing something right.
