cottage pie recipe

I found this in the kitchen of Gordon Ramsay's book heaven. Pancake house is all his food and rest at his favorite, and that in many cases, with wife Tana when eating. Here the difference my recipe adapted from his own country. Added to the equation of cheese - cheese bread, crispy crust is always good, no? I omitted red wine (since I did not have any on hand), but you can add that if you like (about 200ml).
This recipe serves four but I claim that I think the final result can feed six or eight! Next time for my family, I would like to reduce the proportion of meat and potatoes, but maintaining the very tasty, and very little this time.
