I voted Whataburger. I want to try Garage but just haven't made it by there yet.
I just had the Garage maybe a month ago and it was just ok. The taste of the beef was a turn off, it had the taste of supermarket ground beef without seasoning. The rest of the burger toppings were the only saving grace. For that price range S&B Burger Joint, Tucker's, Nic's and heck even Red Robin would be more enjoyable. Part of the fun is tasting all the joints though!
