Sometimes the search for the best hamburger in Austin may take you far afield. Which is how I find myself on a country road 15 minutes outside of Austin proper.
Old Times Bar looks promising. Unfortunately my timing is off as the little country restaurant is closed for the day. Parsing the output of the kitchen online makes me wish I'd shown up during operating hours as reviews are largely positive.
Who's been to Old Times Bar?
How was the burger?
They're flying REALLY far under the radar
