It’s Cinco de Mayo — one of the biggest days of the year along East 116th Street and across East Harlem, which since the 1990s has become home to one of the largest clusters of Mexican small businesses citywide.

Take a stroll for dinner, since most restaurants are gearing up with specials on everything from cemitas to huaraches, aguas frescas to mangonadas. Your walking guide:
