I've read the back story, various publication reviews, and the menu. Frankly, nothing other than the menu matters to me (unless they got crushed by the papers). I didn't bother checking Yelp.
What interested me on the menu were the percebes (goose barnacles), angulas (baby eels), grilled sardines, codfish jowl, bacalao, and other unique and interesting dishes to the DC area. I also liked the fact that they're not really about tapas.
I did start with the percebes and puntillitas (crispy mini squid). The puntillitas are fried squid, crispy, not oily nor heavily seasoned. It tasted pretty good, but lacked any distinctive flavor. The percebes are definitely funky. I think they taste like sea snails. I can see myself ordering them again.
What was really good was gallina en pepitoria - slow cooked Cornish hen in a saffron sauce. It reminds me of really good aji de gallina that I had in Peru. The entire cornish hen was tender and the sauce was splendid (hard to describe the unique flavor, much like I have a hard time describing what exactly aji de gallina tastes like).
I'm definitely going back to try other interesting dishes.
