The Washington Post said these were the best tacos around, so of course I tried them. The Washington Post is right! I especially liked the tacos del pastor. The pozole I thought was only so-so, and overall I am not entirely convinced by the notion that this is a serviceable full-scale Mexican restaurant with mole and the like. The atmosphere is more mom and pop than the web site might lead you to expect. Don’t get carried away here, but definitely recommended, cheap too.
