Calm atmosphere and friendly service. High quality food. A bit more expensive than your average restaurant, but worth it!
The armosphere, the place itself. You can wander around for hours and be amazed by their collection. Don't forget to stop by the sky cafe when it's open!
Whatever you prefer as a drink, they have it (or most of it, since there's a lot of choice!) ;-)
Take away is less interesting when it comes to pizza's: they don't always give you a discount and there's hardly anything on it (if you compare it to the one you get in the restaurant). A shame.
