I am not generally a movie goer. I prefer watching at home where I control the temperature, food, volume, company, and amount of floor stickiness.
That being said, my friends drug me to the Alamo Drafthouse a couple of years ago to catch a movie and I LOVE that place. It's comfortable, the food is edible (not great, but not gross), and I can get completely schnookered while watching their throwback movies or the graveyard shift.
So now I actually hit the theater from time to time.
Literally no. Cinemark theaters AND Alamo drafthouse in Socal, most if not all pretty much have beer on tap and bottled/canned and I can confirm Cinemark even has wines, they just card you when you order. Just go to their website and check. I was there (cinemark) this past weekend to see imaginary, inspite of its poor reviews I enjoyed it for what it was. Alamo draft house theaters only card you when you order alcohol too, I recommend them, their food is actually great too.
I know op wasn't in one of those theaters I was just making the classic 4chan fake and gay joke.
My area is a bit more puritan, and I think they're required by law to be separate entities, so I guess I assumed that was pretty consistent nationwide.
