I don't know DoN, never heard of them. I know the VIE HON parking lot, which is terrible. However, without knowing them, I presume that this is just another German geiz-ist-geil move, so I don't have any hopes.

So, let's use this space to discuss where in the airport one can have a proper meal (and please, people with geiz-ist-geil attitude that eat lounge food only because it's for free, abstain. You deserve nothing better). Taking into account that some options take more time than people sometimes have.

In Zurich: I have had good experiences at Sprüngli when you know what to expect; it's inbetween a quick grab and a meal. Swiss Chalet, well, you need to tolerate heavy food, the quality is okayish. Never really tried the larger restaurants on the main floor, what are they like? For fast food, personally I'd rather grab something from Pret-a-Manger than from Burger King, and I am not a fan of the Marché outlets. None of these are really great, but not worse than most lounge food (I find the FCL food not really bad, but it's overrated).

But other than that, any really decent choices? What about GVA?
