I've never actually had this dressing at the restaurant, but my husband has and HE says it tastes very close. The only thing I think I would change is to put the chopped cilantro in AFTER you put this into the blender. This is my version of a copy cat, but I don't know, because I've never had it. Let me know if you think it is close. I came up with this recipe because my husband does not like the cilantro ranch dressing.
