Sonic

Its fast food so don't expect a fine steakhouse. The food is consistent, and pretty good for fast food. Service is great. Everyone there should get a raise just for how many hats they have to wear. Drink menu is awesome. Hot dogs are good, a little overdone with toppings, but still a good dog. Ice cream is good. Cheese sticks are probably the best fast food ones I have ever had. All the other chains attempts have sucked. Good food, great service.

As far as chains go, Sonic is probably one of my favorites just for the simple fact that you can add just about anything to your drink.  Watermelon, blue, strawberries, whatever you want in whatever mix of drink you want.  

The food is pretty consistent, as is the service, and on a good day you might catch someone on skates delivering your mail if you pull into a stall...
