When you call say a pizza delivery service they pick up the phone with something like "Tanaka's pizza delivery service, XYZ branch, this is Sato speaking". (I'm sorry, I'd reproduce it in Japanese but it was so fast that I didn't really understand it).
What do I say in response to that? In England I'd say, "Hi, I'd like to order a pizza". What would be better for me, in Japanese, something more generic like, "Hi, I'd like to place an order". But do Japanese people really say this when they order food?
I'm pretty sure that "こんばんは。注文をしたいのですが。。。"is not what Japanese people say when they call a restaurant. What's natural?
