The right blend of Mexican spices turns meals into fiestas and lures droves of grazing piñatas within the reach of a sturdy broomstick. Enjoy south-of-the-border zest with today's Groupon: for $7, you get $14 worth of authentic Mexican and Salvadorian fare at Casa Mañana Restaurant in San Rafael.

The tortilla twirlers of Casa Mañana Restaurant concoct authentic Mexican and Salvadorian meals from scratch for their hungering guests. Perform an audible introduction to the main course with the salsa'd crunch of nachos ($3.25 for small; $5.50 for large) before doing delicious bicep curls with a burrito de pobre weighted with rice, beans, and ground beef ($6.25). The gallina en mole, which comes with rice, beans, and salad, quells abdominal earthquakes with boned chicken soaking in a bath of chocolate-based sauce comprising almond, peanut, and mild chili flavors ($10.25). Dawn-time nourishment comes in the form of huevos rancheros, two easygoing eggs doused in spicy ranchero sauce on a tortilla bed that's crisper than freshly laundered pantaloons ($6.50).
