I'm with Pac, I order things I don't normally fix at home. I enjoy the restaurants atmosphere and service as much as the food.
I don't go out to eat anymore, but I do take people out to eat from time to time. It is just easier for me and often times cheaper to take folks out than it is to entertain them at home. Most importantly for me, at this point in my life, it is only one meal instead of a week of leftovers I shouldn't be eating!
The most recent venture was with my sister and one of her children, it was more about the people than the food. Great atmosphere/vibe, great seafood, soggy fries. Something simple like the fries irritated me because I only eat them a couple times each year and I want them crispy on the outside and creamy on the inside. I could have definitely made better fries at home.
