I always like to sit at a table and eat mindfully, my wife Mary Ann who has been with meditation groups often will take her plate to check Facebook or emails or paperwork, even go in a room and watch a TV show on PVR. She knows about mindful eating and has watched a DVD on mindful cooking and eating several times.
I will often just sit in my chair and look out the window, Mary Ann never just sits, she does meditate but that's her timed Zen practice.
Are you a mindful eater ? can you eat without your phone.
