Overall our trip to Momocho was a pleasant experience. The place itself is fairly small and a bit cramped. I wouldn't recommend it if you have trouble walking or are handicapped. Although there is a small lot next door, parking can be a bit tight. The service was friendly and knowledgeable.
We ordered the guac sampler which I would highly recommend, since it's almost impossible to pick one. However at $18 it was overpriced. We tried the traditional, goat cheese, and blue crap. The goat cheese and crab were fantastic. While of great quality, the traditional was nothing exciting. It is on the chunky side. My wife also tried a blood orange margarita which was one of the best she has ever had.
For main courses we had the plato (duck), chancho (wild boar), and atun (tuna) tacquitos. The duck was excellent, especially when accompanied by their bbq sauce. The wild boar was fairly decent as well. It was not very game-y and was perfectly cooked. The tuna was also cooked to perfection and comes highly recommended.
Overall a very solid 4/5 stars
