Jason from I Dream of Pizza just put up his take on Pizzeria Salvo. Thanks to these forums, I knew about Salvo and was able to tweet Scott about it before their trip.
Interesting in that Jason mentions "Our Margherita pie was delicious -- definitely one of the best pies I had during the entire trip", but at the end mentions, "...although I wouldn't put Pizzeria Salvo in the "must try" category"
Either way, it is a favorable write-up about the joint. http://www.idreamofpizza.com/2011/03/pizza-adventures-in-italy-part-5-salvo.html
