To call Tacos & Deli, a one-year-old family-owned spot in the popular nightlife district of Zona Rosa, small would be an understatement. The main dining area contains six little tables, a tiny kitchen, a taco station and a cashier stand, all of which are squeezed into a micro-sized area that in many other restaurants would probably end up being used as a broom closet.

In Mexico, sandwiches generally come in the form of the torta, usually made out of a white bread roll known as a bolillo that has been sliced in half and then filled to the brim with meat, avocado, tomato, onion and sliced jalapeño peppers. In Mexico City’s San Rafael neighborhood, however, a family-owned sandwich shop called La Vaca de Muchos Colores is doing its best to expand the city’s sandwich scene.

Caldos de Gallina Luis – which a friend had been raving about to us for months before we finally made it there – is essentially a street food stand that has been trussed up to look more like a sidewalk café. Just a short walk from the Insurgentes metro stop, the venue is located on a side street next to a parking lot and opposite a sex shop, the glowing neon of the shop’s sign casting its pink light over pedestrians walking by.
