Of the two, Sanborns is the older. It was founded in 1903 by two brothers from the United States as a pharmacy, soda fountain and lunch counter. Eventually the chain was sold to Walgreens, and now it is owned by Mexico's richest man, Carlos Slim.
VIPS is owned by the same company that manages such U.S. chains as Starbucks, Burger King, and the Cheesecake Factory in Mexico.
Alejandro and I usually go out for breakfast on the weekends. Most of the independently owned places in the neighborhood are closed on Sundays, so we have to go to one of the chains. We have both a Sanborns and a VIPS within a few blocks of the apartment. However, the food and the service at the nearby Sanborns are not up to par, so we usually go to VIPS.
VIPS also has a much wider selection of breakfasts, and we have found the waitresses there to be very friendly. A couple of them will come up and say hello to us even if they are not waiting on us.
At the beginning of November we got two of their monthly loyalty cards.
