SA - Chris Madrids is the best I've eaten here.
Dallas - limited experience - Burger House
Houston - Otto's. Best Burger anywhere. This place was always packed when my dad took us there.
Mel's Burger Joint? I've seen it, but never stopped. My sister is the girls JV basketball coach at Cove, so next time I'm up there I'll definitely talk her into trying it out.
Storms in Lampasas is good. Know the kids that work there and get the hook up.
I can't believe someone else said Westgate Lanes. I was thinking the exact thing. They are some greasy goodness. Had one just last Wednesday actually. Still good.
Whataburger has the best fast food burger around. Those are great late at night.
And this thread has made me decide to go get my friend and go to Sandy's. He's not from Austin and it's been forever since I've eaten there.
This is kinda obscure, but the burgers made by Walle at the concession stand at Zaragoza League semi-pro baseball games are the best I have ever had. The field is located off East 7th street. Most of the games are played on weekends in June and July, all day, beginning at 10:00 or so. They're worth the trip.
It took burgers to lure me out of the shadows where I've been lurking, but as far as killer burgers are concerned, I've gotta go with:
Houston: Pappas Burger (I know, I know... it's not the same atmosphere of any of the Austin locations, but it's Houston). I'm starting to wonder if it's a coincidence that Pappa's B is right next door to Pappas Steakhouse (rediculously good steak)...
Austin: I've gotta give Huts the nod, but the lines are long and occasionally I've had a dry burger... Burger Tex is pretty good too (or the bulgoki option)... and rounding out the top 3 is probably a three-way tie between Crown, Posse (burgers not fries), and Dirty's.
Hut's and Dirty's are 2 of my favorite places for a burger. They are both pretty good priced, although Hut's is a bit more money, it is still cheaper than fuddruckers.
Dirty's also has some badass milkshakes...mmmm
Hill's also makes some good hamburgers....mainly cause the bun they use.
Chester's in SA town is probably one of the best hamburger places I've been too. They make an awesome chilli cheeseburger.
I might have been smoking crack when I heard this, but someone told me about a Korean (?) restaurant in Waco that, unbelievably, had incredible hamburgers.
There is a new place in Lago Vista, Bam's Roadhouse Grille that has what I consider to be the best burgers in the Austin area. If you are heading to the lake or golf, I highly recommend you give them a try.
