Moles are the prize here and, to make things easier, a tasting menu allows you to sample all seven of the revered sauces along with tortillas for dipping. The mole negro with chicken rules OK. It also offers tasajo (thinly sliced grilled beef) done 15 different ways. Grab a table on the rooftop terrace.
There's another Los Pacos – older, more local and more family-oriented – in the Colonia Reforma neighborhood in the northern suburbs.
