San Antonio is one of the largest cities in the United States, so you'll find no shortage of places to eat, drink, shop, explore, or be otherwise entertained.
Casa Azul is only a mile or so south of downtown, and smack-dab in the middle of some of the best restaurants in the city.
A quick walk across the river will take you to the Blue Star Arts Complex.
You could also continue walking up the river into downtown San Antonio.
San Antonio is home to several excellent art museums, including the San Antonio Museum of Art and The McNay Art Museum.
And so, so much more besides.
