This is an information that I pass on to you, but that I haven’t tried first hand. It’s something I learned watching TV a few days ago, and since I think it is a quite smart business initiative, I thought you may find it useful as I do.
There’s a Lasagna fast food in Rome, near the Colosseum, called Lasagnam, which sells fast, genuine dishes freshly made every day. Fatto a mano con amore ogni giorno (hand made with love every day) is their motto and according to the reviews on Tripadvisor it is highly rated (4 stars out of 5).
They make 10 different kinds of lasagne (one even with boar meat)
And specialties like fiori di zucca (whose recipe you can find on my design blog)
PS: They also have a Facebook page in case you want to start following them.
