Sundance is probably the top of the line for theaters in Madison. It has a very contemporary lobby, a coffee bar and an attached restaurant/roof top bar. Not to mention you can take your food and drinks into the movie with you! The seating is nice and spacious too, not so crowded that you are almost sitting on the person next to you.
The price is a bit steep but being able to choose from Hollywood hits to indie films is what makes it a nice change.
