On Friday evening in Jackson Heights, families crowded sidewalk tables outside Taqueria Coatzingo. The restaurant has doubled its tamale selection since early summer. Servers said they now offer regional dishes from Puebla and Oaxaca, alongside the usual tacos.

This expansion reflects a broader trend across the city. In Sunset Park, a new wave of Mexican bakeries has appeared since June. Pan dulce and tres leches cake are available alongside specialties like tlayuda. Restaurant owners cite both customer demand and new arrivals from southern Mexico in shaping menus.

The growth comes amid a tense political climate. Earlier this month, community advocates reported an uptick in visa-related questions from kitchen staff, citing concerns about work permits and documentation. Despite these pressures, the number of Mexican restaurants in the five boroughs remains at a high point, according to city licensing records reviewed last week.

Restaurant operators describe a balancing act. Some worry about the impact of public rhetoric and stepped-up enforcement. Others point to a more adventurous customer base, willing to try less familiar dishes. On Roosevelt Avenue, Sunday night lines at birria stands now stretch around the block.

Chefs say the moment is complicated. Many are expanding menus, but also watching for shifts in labor and policy. For now, the city’s Mexican restaurants remain busy, offering a wider range of flavors than ever before.
