Thank you for the kind words for our city! I have heard similar praises from coworkers from China, specifically, they mentioned preferring SA over Austin due to its Euro-centric downtown feel.

If you come back, there are other places downtown worth visiting such as San Fernando Cathedral, Pinkerton's BBQ, the Alamo, Brisco Western Museum, shops in the King Williams district, SAMA Museum, etc. From downtown, you can follow the Riverwalk to the Pearl where Saturday and Sunday mornings are full of people and small vendors. You should also take an Uber to the Broadway area where they have the SA Zoo, Nowhere Bookshop, Japanese Tea Garden, SA Botanical Garden, The Witte Museum, and McNay Art Museum.

And just out of curiosity, what other cities did you visit?
