Pizza Blitz isn't bad, though I think it's gone downhill somewhat (www.pizza-blitz.ch). They're usually pretty quick, unless they're overwhelmed with orders and they'll tell you that, too.

Mosi's (www.mosis.ch) shouldn't really take the blame for portion size though they should take the blame for cold orders. The restaurants control the portion size, not Mosi's. Their service is hit-or-miss. Most of the time they get it there fairly warm, but not always. Of course, they do worse in the winter when it's cold out. They should get ovens for the car to keep the deliveries warm like some places in London and the US do.

I've heard some people say Dieci (http://www.dieci.ch/) is pretty good, but I've never ordered from there.
