I used to think that this place was not as good as In'n'Out but after coming here a few times, I have seriously changed that opinion. Meat is corn- or grain-fed (every time I ask I get an "I don't know but I know it isn't grass-fed."), so no 5-star. Veggies are pretty darn fresh, fries are delicious (although nobody has been able to tell me what kind of oil they're fried in yet).
The flavors here are much fresher and more distinct than at In'n'Out. Less of the over-powering fake-cheese and sauce and more of a subtle mix of all the veggies and the beef, which I find to be a much better overall experience.
Best part: when you ask for fries they fill your cup "fullish" with fries, set it in the bag, and "top it off" by dumping another entire helping of fries on top of your fry cup. Expect the bottom of the bag to be completely filled with fries regardless of the size you order.
