Ossobuco alla milanese which is commonly referred to as "osso buco" or "osso bucco", is a traditional dish from Milan, Italy the capital of Lombardy.
It is made using braised veal shanks and often garnished with "gremolata" which is a mixture of parsley, garlic, and lemon peel. It is also often served with saffron enhanced rissoto.
Their are many styles in which osso bucco is made and depending on tradition some people used tomatoes and some do not.
Here are a few recipes that you can look over and decide how to best prepare the dish:

My recommendation for a wine pairing would be Barolo, Barbaresco, or Brunello di Montalcino. If you low on money than I Barbera d' Alba will work too if you get the right one.
