Some of the best tacos on this list come from a space – Chilango Express – that’s adjacent to a gas station. Fancy settings are no indicator of quality food. Peek around the counter and you might see a woman mixing together masa harina, salt and warm water to make corn tortilla dough. The freshness of that base ingredient (which yields a fluffy, light tortilla) combined with big meaty chunks of pastor is taco ecstasy. Come early on weekends for the lamb, a dynamite taco filling.
