Has anyone worked at any chain restaurant that makes tortilla chips?

[green97]

I know how to make tortilla chips and have made them before but I am not satisfied with the results. They come out either too brown and crunchy or to soft and not quit done (If I try to not over cook them). I am wondering what Is the method that Restaurants use to make there own chips. The ones that come out crunchy and light, although they do come out oily sometimes. has any one worked there and know how they make them that way. What Is the "secret" to It, I guess you could say. Has any one been a chef there and know the temp of the oil and maybe a technique or something? Thanks
