The Stockyards is a fun place to hang out with loads of shopping, restaurants, bars, and the rodeo. Depending on what time you go, you might catch the Longhorn walk! Wear some cowboy boots and have fun!
Sundance square has a fair share of shopping and restaurant locations to check out.
Grapevine Mainstreet has various types of shops (there is a cool retro candy shop!), various restaurants, and has a fast train that goes all the way down to the Stock Yards. There is a vintage train as well! Check out the website if you are interested in taking a train.
