For being old, that's a hard one to think about. There was this french restaurant in Toronto that had the best food, Boston's Legal Seafood had the best clam chowder, and Texas' Land and cattle has the best steak.
I guess the best experience I had was when my future husband and I went out for lunch in Illinois. The restaurant was nice, the service was good but the funniest thing was my arm was in a sling. Ok, you might not find that funny, but when you live with a one armed man, it is. We both ate left handed and got the weirdest looks from people. New love, and we just had to giggle with eachother during the whole meal.
