We took our son to a movie here a few weeks ago and found no signage regarding firearms. I had a quick look on the way in as we were running a bit late. On the way out I looked at each door and window at the entrance and walked through the lobby and found nothing.
As a bonus.. They have really great wide reclining comfortable seats!
We had a great time and our son loved watching the movie.. The Nut Job. We did too!
