The guy actualy opened a thread long time ago on this forum about getting his oven approved.... I reccomanded for him to talk to Il Pizzaiolo. That company is also behind the 2-3 business names that made the oven at Donna Margherita in London, which is now falling down.....
All the marketing bit around that company (it is a franchise) is all b......t. They have also opened a branch in London (Hampstead).
