I've only eaten at 5 Guys once. Since then, they have opened one just a half-mile from home but I haven't gone. I recall the burger being good, but kinda steamy wet and sloppy. I could be wrong, but I also believe it was almost twice the price of what In-N-Out or Habit Burger is. The fries were better the In-N-Out is terms of size, both how they were cut and serving amount.
Out of all of them, Habit Burger strikes the right note of quality, serving size and price for my tastes. I used to like Fuddruckers for letting you dress your own burger and them cooking it to your liking; although one time I ordered it rare and it was indeed that- cold and raw in the middle, a little creepy even for a carnivore like me. They closed the one by PV Mall and I hadn't seen any driving around town. I thought they went out of business, but I see that there are still 4 in metro Phoenix. Gotta try 'em again.
There's a new place at Scottsdale & Shea called Hopdoddy's from Austin, TX. I haven't tried them yet, but will report back when I do.
