I have been eating at In-N-Out since the early 60s. Their hamburgers are fantastic. But today the French fries were the worst I've ever had. I had to send them back twice because they were burnt. Each time they came back burnt. I'm not sure if this was because they did not change their oil when they were supposed to, or if the heat was set too high. The location that I went to was the one that's located on Francisquito and Vineland Avenue in La Puente. This took place at 11 o'clock this morning.
