Didn't get the chance to do much as I was just here for another Killers concert the night after Austin!
Airbnb - There was a nice Airbnb near the venue, Dickies Arena, with a guesthouse above the garage.
Goldee's BBQ - Stopped here on my way up from Austin to pick up lunch for the whole crew. About an hour waiting in line but it was well worth it, especially since I was getting $100+ worth of food. I'm generally not a huge BBQ fan, but Texas does it right!
Whataburger - A famous American burger chain from Texas. Their fries and milkshakes are top notch.
