You have to understand that Frisco and Allen are the ultimate in plastic suburbia. Plenty of idiot posers with disposable income for a fast-food burger from a chain of restaurants that has gotten lots of publicity. They will buy what they are told. The best burger joints are not chains - they are usually the mom&pop, whole in the wall places you have to seek out. When you find one of those with a wait to get a seat, you know you are in the right spot. In-and-Out burgers are not bad, but nothing spectacular. Sonics just plain suck. Five Guys are nothing special, I found them dry and boring. Smashburgers are pretty good, I have been back for more. There is a local spot called Burger Guys that is pretty impressive. The first time I went the line was out the door and I had didn't have time to wait. Beck's Prime makes good burgers, but are a bit pricey for what you get. In Texas, if you want just a drive-thru burger, Whataburger is hard to beat.
