I do not have an iron stomach, I got very sick on trips to India and Mexico. But I was much less careful on four trips to Egypt and I've never had a problem. (knocking on wood!)
I am a vegetarian. I ate pretty much anything I wanted from anywhere including street stands drank a lot of juice and really didn't worry about salads.
Of course its always a good practice anywhere to try and look at the food that's about to be served to you. If it looks like its been sitting out, pass on it. Choose places that look busy.
I've also heard that the tap water varies in Cairo. Any of the areas that I've stayed as a tourist seem to be fine. I've always stuck with bottled water for drinking, but never worried about brushing my teeth with tap water and I don't recall that I was really offered drinks with ice in them. I would recommend being more careful about this when traveling outside of Cairo though.
