Overall - terrible service. If I could rate lower than 1 star I would.

My wife and I waited for 30min after sticking us in the very back so cleverly named "the garden" (spoiler: no actual garden only tables and chairs placed outside behind the restaurant in a secluded area). Staff kept saying "one moment one moment" but that moment never came. They sat 5 more tables within that time. Not once did they come to check on us or to take even a drink order. To add insult to injury, "the garden" is next to the kitchen where waiters enter and exit with food. Not a single one made eye contact with us.

We left without ordering.

Point-of-note: Interestingly, before the staff sat us, the waiter asked us if we spoke Italian (despite my name, my wife and I are both asian ethnically). I said we didn't, and he said "but you are in Italy" in a disapproving tone. I noticed that everyone they sat with us were foreigners, including asian. Not a single local Italian table. I could tell because I could hear the language people were speaking.

Instead we went to Trattoria Osenna - and fortunately we got a nice table INSIDE. The staff were very helpful from the beginning and quite kind. Our waiters spoke very good English and kept checking on us despite being a full house. This restaurant is on the main street while Al Vecchio Forno is 3 rows back - not sure if this is an indication of success, but if it is, then it shows. My wife and I had a fantastic meal at Osenna and highly recommend it.
