Destination
a walk downhill
A large going-out area with great restaurants and restaurant concepts. You could eat somewhere excellent every day. Walk down, and take an Uber back up the hill.
El Poblado
A restaurant in the going-out district. It is very open, with great lamps and lots of lights. I had a fantastic steak and a wonderful cocktail there, and I can recommend it.
I took both around the city. It is easy to reach them, and an Uber back in the evening is safe and cheap.
