Back in Texas, I enjoyed Whataburger quite a bit (although eventually I came to enjoy the chicken boxes a lot more than the burgers.) Here in Utah, the food scene is generally pretty bleak, but we have some good burger joints around. My favorite is a place called Astro Burger. The burgers are tasty, the fries and soda are superb, and the staff is always excellent whenever I go there. Only drawback is that it is a bit pricey for fast food but it’s a good once-every-two-weeks kinda meal.
As for fast food you can never go wrong with McDonalds
i'll get an in-n-out burger every once and a while because they're open past 11 (when i get off work) and they're cheap as balls but the fries are the worst thing there
The local burger chain here is called Dick's. Everyone pretends its good, but its not.
“lamburgers”
Edit: most of you probably don't know what the beltline is
An Indian chain called Good Flippin’ Burgers has really good burgers.
