The Tropical Smoothie Cafe inside Red Rock Casino at the food court. Its one of those places you just come to get a quick drink, or kill some time before the movie starts.
Prices appear to be slightly higher than other locations, $1.50 for some drinks, making the drinks $6.50 for some before you add any extras. I guess you got to pay more for being inside a casino and by a theater.
Order. Pay. Wait. Drink. Enjoy. Nothing exciting or bad about this place.
