Not much to say that hasn't been said by others. This is your run of the mill In-N-Out, but run of the mill In-N-Outs are fantastic.
I got a burger, fries, and a shake. The burger was exactly what I expected--really tasty and satisfying. Fries were great and the shake was the best shake I've ever had. They get it so creamy--not to the point where it's hard to drink, though.
I wish we had these in North Carolina. Best part of the west coast!
