I've had two experiences with the burger at 5 Guys here in Phoenix. One great the other average.
Even if every time the food was great I would still have to agree with those who have questioned the value. I treated my friend and 2 drinks, a little burger, a regular burger and a fry came out to just shy of $20! There is no way that's a good value for a burger.
For those who like them it may be worth it but a good value it is not.
