I don't really understand how some people call this place "expensive": it's an all-you-can-eat deal…read morefor like 12€, it's great! Sure, it gets a bit more expensive on weekends and at night but hey, it's easy: don't go on weekends or at night.
The food is really good, some dishes are better than others but there's a lot of stuff to choose from so if you don't like something you'll probably find something better next to it. They change dishes often so if you eat there once and then go again the next week you'll probably see different dishes. Food and desserts are included in the price, and so are coffee and tea. It's one of my favorite places on Earth for a reason!
