It is possible that I've had a better burger and just don't remember, but there is a place in Arlington, TN called Off the Hoof and their burgers are great. I'm usually not one to go out for a burger 'cause I usually think that I can make better at home, but I look forward to Off the Hoof at least a couple times a month! You can order 4 oz., 6 oz., 8 oz., up to 16 oz. and then pick your cheese, add thing like grilled onions, jalapenos, etc. They serve onion straws, breaded french fries, cheese fries, and the frickles (fried pickles) are great too. Are you hungry yet?
(Those 12 cent burgers at Dairy Queen when I was a yound kid were pretty good too, but it was probably because that was about the only place where we got to go out to eat and that was rare!)
