In'n'Out is "OK". I rarely do fast food, but I tried it when out that way for lunch. Wendy's to me is about as good.
Five Guys is OK. We have a local chain called Killer Burgers which is pretty good, but they sell $8 burgers and up.
Burgers are so quick and easy to fix at home I rarely eat them out unless traveling, and then I'd rather do a samwich.
