Where is Your Go-To Burger Pit Stop in Austin?

Austin burgers run the gamut from gargantuan to gourmet to classic, and that doesn't even include the endless veggie options. There's plenty of great burgers to be had at Austin's finer restaurants, but sometimes the burger is best eaten on the run. Eater wants to know: where's your go-to burger pit stop in Austin?

Burger pit stops can be drive-thru, or counter service, or even just in a super casual bar where you stop for a burger and beer. The burger should actually be good; superior fries and/or shakes is a bonus. Anywhere with lines is disqualified. Leave your thoughts in the comments, or hit the tipline.
