Glory87,
I just saw your photos!
WOW!!!
We generally go to late afternoon matinées after having gone out for a nice lunch, so we're too full to eat any of the crap in the theaters! But I have to admit there are times when I have had the popcorn. We'll get one large to share (between 4 of us) and two drinks. We never finish the popcorn!
Also, this theater near our house allows you to bring in outside food. They have no problem with you stopping at any of the restaurants and bring in the meal to eat while watching the movie. It's actually weird! I've heard of people bringing in pizza! The usual is something from Starbucks, though.
