Many thanks for all the advice. Too much food too little time, but here is a quick summary.
We did Chilpancingo on Tuesday, getting there around 9:00 because of wind and repair delays on United.
Chilpancingo disappointed me, though the other four were happy with what they ordered: Tuna, Pork Chop, Shrimp.
My ostrich in mole sauce was supposed to be medium rare, but more like well-done. The mole suace was dull.
My appetizer of sopes surtidos was mixed. The best single item that I tasted was the caesar salad.
Next day did lunch at Nuevo Leon, incomparably better. The amuse bouche of chicken soup was first rate, better broth than I had at RGordon Ramsay on Royal Hospital Road. The mole sauce was rich with chocaolate and cinnamon, truly delicious. The tongue was tender and tasty, superb dish. Even the rat tasted good.
Wednesday night we tried Operetta, but it was packed with skin-headed beer-drinking youn worker immigrants. It was drink two, get one free. Very little food seemed on offer. So we went to my uncle's favorite, Mirabelle. Not my favorite, but he was happy.
