What can I say--I'm just glad this place exists. If you are a Taco Bell lover you'll get a kick out of stopping by the Cantina, even if you don't order one of their spiked slushies. When we visited it was under construction so the patio was pretty hot and there was only one bathroom but it looks like they are making some improvements and expanding.
Prices are comparable to regular Taco Bell prices and there were a couple of menu items that I haven't seen at regular TBs. The food is your standard Taco Bell fare so if you don't like TB then you can pass but if you do, or if you'd like to spend less than $5 on a meal in Vegas stop by!
