My wife said that this was the best pizza she ever had. We came at 5:30 pm and by seven o'clock the place was packed with people waiting. We shared the special pizza and I requested Regianno on the top. This is very expensive where we come from in Australia but they had a Parmigiano wheel on display as you walked in. Giovanni is in the heart of old town Praha and one hundred metres from our apartment in Arcadia Residence that is also in Kozna. Our manager recommended this joint to us. I must warn that if you come later, the service may be slower. The bartender refuses to speak English, German or any other language which I can speak. Czeck is the most difficult language for me but the waitresses speak fluent English, Dutch, German, French and pretty much anything I threw at them.
