Located across the street from the amazing Cosmo Hotel, Rockin Taco provides your basic American mexican food with great prices (well for the strip anyways), friendly service and great frozen margarita drinks. The location has a line for drinks only and this is by far the one to be in, the service here is great. On Monday 2/25, early evening, the lady working was fun, polite and energetic. The service from the food line is good, but very basic (2/26). Overall, I recommend this place! The $2 dollar taco promo gets you a good basic small bite to eat on the strip with your basic bar style food. Nothing to write home about, but much better then Taco Bell!
