The state of being while eating something so good (or long-anticipated) that one loses some or all awareness of what is around him or her. Talking diminishes to a minimum, and this may also be accompanied by a tremor-like shaking in the legs. One experiencing a food trance tends to eat quickly, so as not to lose the pleasing taste of the food being consumed.
"Sorry, I wasn't paying attention. That steak put me in a food trance."
