I know what you mean Star! I think it's the bread. I never really noticed it until they put one in our mall. You walk by it and all of a sudden you are hit with the smell. It makes you want to go to Chick Fil-A.
We have a pseudo grocery store here called International Market. They sell imported fruits and a lot of the cultural stuff that's hard to find in your regular grocery store, but they are really tiny. They make the best gyros!!! I have yet to find a place that makes better!
I totally forgot my favorite convenience restuarant of all time, and I eat there about twice a week! I don't really consider them fast food, but they're not a sit-down type restuarant either. I absolutely love Panera!!!
Also, along the lines of fast food, there are times I really crave some greasy chinese take out!
