I usually like to start or end (sometimes both) my trips to Vegas with In-N-Out simply because it never disappoints. My go-to order is the #1 combo (double double "animal style", "extra toast"). You can taste the freshness of the meat patties and the proportions of the other ingredients (animal sauce, grilled onions, lettuce, tomatoes) create a perfectly balanced burger. The taste of the fries have grown on me over time and complements the burger well. I have yet to discover another burger fast food chain that can replicate the quality, value and consistency of In-N-Out!
