Let's now turn to Mexico City, where one business is serving car-owners by day and foodies by night. Alasdair Baverstock takes us there.
An auto mechanics' workshop in Mexico City, complete with hydraulic lifts, transmission changes and car wax.
But look more closely, and some things might appear out of place.
At 7 pm, the mechanics' closes for business, and an hour later, reopens as a taco stand - and one of Mexico City's most popular at that.
ISMAEL TILOSA EL VILSITO MANAGER "For people who come for the first time, it can be very strange that this place is a car mechanic's in the day, and a taco stand at night. It's strange, but very interesting. But the people who come regularly, it's the flavor that keeps them coming back."
Located in La Narvarte district, El Vilsito has been in business for 33 years. The stand serves a Mexico City staple, tacos al pastor, marinated pork stacked shawarma-style, grilled, and then eaten in a corn tortilla. People come from across the capital to eat here.
ALBERTO SALAZAR EL VILSITO CUSTOMER "It's the simplicity of the place. You show up, hang out beside the grill, and eat where you stand. And the sauce they make here, for me, it's the best in all of Mexico."
Today, the shop's fame has spread, and the operation has expanded to accommodate the demand. The profits have allowed the owners to open two more formal restaurants close by.
Nicolas Garcia is a Mexico City food tour guide, and for his clients, this is an unmissable stop.
NICOLAS GARCIA MEXICO CITY TOUR GUIDE "It's the type of dining that Mexican people love. Instead of going to a restaurant and sitting down, people love eating tacos like this, on the streets. And it's very common that popular businesses start like this; it's a family thing, somebody starts serving a good dish, and word starts to spread until it becomes like this, a successful business."
ALASDAIR BAVERSTOCK MEXICO CITY "The owners here at Mexico City's transforming shopfront say that while the success of their business has been boosted by the novelty of the enterprise, it's the quality of the service in both operations that guarantees their financial future.
