There is nothing wrong with a solid neighborhood taco spot. However, some places are just that,…read morerather than being foodie destinations. Onions and Cilantro is solidly in the former category rather than the latter.
I ordered a two-taco dinner, with one Al Pastor and one Steak. Both tacos were simple as can be: protein, onion, cilantro. The veggies were fresh and in good balance. The proteins were in ample and not overloaded amounts, but were unfortunately underwhelming. Other than being well-roasted, the flavor was not prominent. The Al Pastor especially disappointed, since not only was evidence of pineapple missing, so was evidence of marinade. With this, both tacos felt dry; a case of sauce required as opposed to sauce-optional.
I've no complaints about the rice, and the beans with bacon were, well, beans with a little bacon. They could have done with a little less water and more bacon, but I'm not too upset about it. For beverages, I was able to try two of their Aqua Frescas - nothing to write home about, but also not overly sweet and with good flavor. My favorite thing of theirs was the Pico de Gallo. Bright, fresh, flavorful, a little herbaceous, just what I look for in Pico.
While not very busy at the time, the service was friendly and relatively quick. The prices are more or less in line with the market, so I can't complain too much without being generally up in arms about the market as a whole.
Final verdict: Onions & Cilantro failed to impress, but this is partially on my part for expecting mind-bending food. Protein, onion, and cilantro are good and fine, but be prepared to sauce for (rather than 'to') taste.
Would recommend?: Ehh... if you're already local, and are craving tacos, it beats Taco Bell. Otherwise, there are better places out there.
Would return?: Honestly, no. This is both due to distance and a less than stellar experience.
