As a well known poser & imitator of all trends... I would like to piggy back on the other 100 Things You Must Eat lists.. applied to Mexican gastronomy. Please nominate one... but please choose diligently... only the best of the best!
My nomination is for Pato en Mole Verde con Flor Rellena (Duck Braised in Green Pumpkin Seed Mole served with Mexico State style Goat Cheese Stuffed Pumpkin Blossoms)... I can't remember the name of the fonda but if you are ever in Almoloya del Rio, Edo Mex (its on the road that goes through Desierto de los Leones & San Miguel Ajusco towards Toluca)... you have to stop & ask for this dish (its a very common regional specialty prepared with locally harvested duck).
