Yes, we say a special prayer before each food (they different blessing depends on what food you are eating), and then a prayer afterwards (also depends on what you ate).

There is a more extensive after blessing if you had bread, you normally say it from a little booklet (takes about 4 mins or so).. Funny thing is my son loves to get a booklet and sway back and forth pretending he is doing it - it is very cute! He often does it to each book he picks up also.
