I know that seems like heresy to In N Out lovers, but just wait til' you try it. We tried P. Terry's after after driving past their fun retro looking building on the corner of Barton Springs and Lamar a few times and haven't stopped going back since. I'd almost be embarrased to know many times we've eaten out as a family there in the last year except that they use 100% all natural Black Angus beef, Buddy's natural chicken, and Gardenburgers, they even offer wheat buns if you prefer which I haven't tried. You really can't get a much healthier hamburger! They're fries are fresh cut and they're milkshakes are addictive. Their menu is simple and inexpensive (still), they even boast to have a secret menu though I can't seem to find it on the website. We are devout devotees and even showed up early on their one year anniversary for free t-shirts and cookies and then came back to eat later. Yes we're P. Terry nerds, and probably one of their best marketing solutions besides their location - we've told so many people about them and brought so many friends here, more than any other place in Austin.\r
I was just reading some of the reviews and wanted to add if the kind of burgers you like are fast food hamburgers or greasy hamburgers dripping with fat then, no, you will definently not like these ones!
Pros: healthy, mostly natural, great outdoor seating area with play area for the kids, fresh, DELICIOUS
