Anyone have Texas Land and Cattlle Wedge Salad reciepe?

Know it's just iceberg lettuce, bacon and bleu cheese dressing. Need dressing receipe and wanted to make sure there or no secret ingedients! Thanks!

I have never eaten at Texas Land & Cattle, but this recipe is from the Perini Ranch Steakhouse (Buffalo Gap, TX) and is very good:

1/2 cup mayonnaise
1/4 cup buttermilk (shake before measuring)
3 tablespoons extra-virgin olive oil
2 tablespoons sour cream
2 tablespoons red wine vinegar
3/4 teaspoon minced garlic
1/8 teaspoon black pepper
1 cup blue cheese crumbles, plus 1/2 to 1 cup for garnish (optional)
1 head iceberg lettuce, cored and quartered
4 slices bacon, fried crisp and crumbled, for garnish (optional)
12 to 24 teardrop or cherry tomatoes, halved, for garnish (optional)

In a blender mix first 7 ingredients. Carefully fold in blue cheese crumbles and refrigerate for at least 2 hours, preferably overnight. To serve, put iceberg wedges on soup plates or dinner plates. Spoon on dressing and garnish with additional cheese, bacon, and teardrop tomatoes. Note: Perini’s actually does a tossed salad, but this dressing goes great on a wedge too. Serves 4.
