They did however confirm that their Penne Arrabbiatia is vegan if ordered without cheese.
If you would like to email Prezzo to let them know how disappointed you are that they use egg and milk in their dough and sauce then they have a contact form here: http://www.prezzorestaurants.co.uk/contact
In the meantime why not visit Pizza Express , Strada or Zizzi!
