We've had a burger invasion here in DFW the past year or so. In 'n Out, 5 Guys, and Smashburger have all opened stores just a mile or two from where I live. Del Taco as well, but alas the Ortega Burger is long gone. I thought 5 Guys was quite good, In 'n Out rather disappointing, and have yet to try Smash. None of them have knocked Whataburger off my #1 spot, though.
Meanwhile, Trader Joes is opening up across the street in about a month. That should be another interesting experience.
I am not a man! I am a free number!
