4 stars simply because I AM A FAN! I love love love the In-n-Out double-doubles and the animal-styled fries! This location near the Strip was busy. I had waited 15-20 minutes in the drive-thru past midnight; the line was long but the foods were totally worth the wait! Juicy meat patties, melted cheese, and the "Animal" sauce, OMG!! Just delicious! I wish the burger chain would come down to Houston, TX just like Carl's, Jr. I keep my fingers crossed.
