RangerSteve- for a brief while, maybe 20+ years ago, there was a small Mexican 'eatery' in an abandoned Dairy Queen building in Arlington VA. which served food like that. The family that ran it was from the Monterey region, which is north of Yucatan, of course, but they had very similar recipes to those you mention. I ate there several times, exploring one wonderful 'different' dish after another....then one day I tried to take some friends there, only to find it empty. I guess it just wasn't the food people expected to find in Mexican restaurant...or maybe they actually moved to a 'better place'....I just never found it.
