Torta Milenese - This sandwich’s roots go back to Italian scallopine or even Austrian wiener schnitzel brought to Latin America by European immigrants. The cozy taqueria in this popular Mexican grocery store has lunchtime lines that curl down the aisles. Cheese, tomato, and avocado top crisp warm steak on a big puffy bun, a meal-sized combo garnished only with slices of cool cucumber. ($3.50)
