I think Alamo Drafthouse in Austin is doing it right: 1. Food & beer/wine served with movie -- convenient and much preferable to overpriced popcorn. 2. Cellphones must be turned off. 3. They take talking seriously, and preface each film with a strongly (and amusingly) worded statement to that effect. 4. No babies allowed except on specified baby nights. 5. Creative and fun special events, such as quote-alongs, sing-a…
I went to an Alamo in Houston and while I liked the concept, the theater was a bit dank (which I worry is an inevitable result of serving beer and food) and not a place I'd prefer taking my kids --- which is relevant because "family of four" seems to be the core market for blockbuster films. I like Alamo, don't get me wrong, but there are downsides to the model.
I haven't been myself (since I like Alamo just fine and only go with friends) but you might want to check it out.
