We had one here in Burnet. It closed a few months ago after being open for about 10 years. Seemed like they always had a hard time getting people to work there. I believe they even posted jobs that started at $25 a hour to try entice workers to apply.
Burger King also in Burnet didn't make it due to the same situation but also you already have Storm's and Bill's here that are the best spots for burgers.
