There's a Mexican place that opened very close to me, and I've been a bit bewildered by the general lack of flavor in their stuff. Examples would be their barbacoa, birria, pastor, chicken tinga, and carnitas. Funnily-enough, they load up the spices in their ground beef, so that's most usually my protein filling. 😕

I really don't know quite what to say in trying to suggest to a Oaxacan-style restaurant that their meats need more spices...
