Five Guys is pretty good, but I prefer In-N-Out. One reason is that Five Guys is waaaayyy more expensive. The burgers are good and the ingredients seem to be fresh, but I personally prefer the burgers and fries at In-N-Out.
I've tried them in Huntsville AL before. They make the best veggie burgers around. You can't tell the difference! The fries are also delicious. :-) Most veggie burgers are made with soy. Soy is a good source of protein and helps in the fight against breast cancer. That's good news!!!
