Chilangos is fine proper Mexican food, but IMO, still lacks a bit of the nuance and depth of the sort I’m familiar with. I wonder why that is, because generally speaking, Mexican food is pretty “simple” overall. I think I should quickly caveat that generally when Texans say ”Mexican food,” we’re actually referring to Tex-Mex. Thing is, Mexican food just isn’t really that common in Texas, even amongst the Mexican diaspora, outside of things like tamales and perhaps tortas. This isn’t to say it doesn’t exist, but OP is almost certainly looking for Tex-Mex and just didn’t articulate the distinction because colloquially, “Mexican food” is an umbrella term in Texas. I just responded in kind with the terminology they used.

The closest thing to what OP is looking for are going to be the enchiladas verdes at Casa Tequila.

I’m pretty “take it or leave it” on most Mexican food, but Tex-Mex kicks it up to 11, where it’s one of my favorite cuisines. I still do find it a bit odd that it’s so lacking - even just one restaurant - up here. Although like I mentioned, I think Indian food rather fills that niche of “flavorful, spicy, deep, nuanced, comfort food featuring strong spices, protein, rice, and soft bread.”
