Pizza Hut, Copenhagen
In some restaurants (especially in Chinese or Indian) you can find the sign "eat all you can" for a fixed amount of money. The same rule has Pizza Hut if you go there till 3 pm and you can eat all kinds of pizzas displayed in a buffet.
Also check various combined "meals" because that's a good way to reduce your lunch cost as food and drinks in Copenhagen are very expensive ...:)
Favorite Dish: American pizza of course..:) My favorite.
