I haven't seen a Whataburger in years. Around here if you want a fast food burger that is still what you would calla burger, it's all about Carl's Jr. Wendys used to make a decent burger but all of the Wendys around here have been transformed into Arbys.
Honestly I think Wendys has better burgers then Whataburger. Never been a fan. Steak and Shake burgers are really good, but I don't really lump them into the McDonalds, Burger King, Wendys, Sonic, Whataburger type of food.
If I want a really good burger I go to 5 guys burgers and fries or CheeburgerCheeburger. Not really a fast food chain like Wendy's etc...but good burgers.
Whenever I'm on the west coast I go to In and Out...those are some damn tasty burgers.
