I like Fatburger even though I should not be eating this stuff at all.  It's the only fast food burger joint with real meat that is seasoned.  It takes a while for the order to come up but it's good. This is my favorite fast food burger.  The burgers come in at least 4 sizes. We got the large and it was veeeery filling.  Even the medium is filling. Like everything in Vegas, it's pricey- we paid almost $40 for three people.
