In Vegas, this is the text-iest of all theaters. Other patrons may annoy everyone else while management allows this to happen. They will look in all bags for outside food. I don't mind paying 5 bucks for a large soda if I'm only spending a dollar or two to get in.
2 bucks is perfect, and if it is Tuesday, you can do Taco Tuesday at Del Taco down the street, then hit up dollar night at this theater. If you miss a movie in theaters, this place is great too catch them on the big screen.
