I've only been to 21+ showings, and it really doesn't get much better than a child-free movie experience! I rarely go to regular movies anymore since shows are filled with obnoxious teens or people bringing in infants because they are too cheap to hire a sitter.
The movie selections are great. I haven't seen any of the indie flicks yet, but I loved watching classics like "The Big Lebowski" and "Dazed and Confused" on the big screen. It's also nice not having to watch commercials or asinine previews before the show.
The wine selection is small but solid. During my last visit, we had a bottle of Shebang! which is a great value wine. I'm not a beer drinker, but my sister and brother in law were happy with their taps.
FilmBar has a good selection of candy and great popcorn. Really, it's a better movie watching experience in every way imaginable.
