Every time I was on 17th I would pass Fiore and say to my boyfriend, "we should go in there sometime." After a hundred or so times of saying that we finally went in. I don't think I could really say anything bad about Fiore Cantina. I had a pleasant enough experience there one afternoon for my boyfriend's birthday lunch.
It wasn't very busy in the afternoon, so it was quiet and intimate. It's been my past experience that when a place is busy your waiter seems to pay too much attention to you due to boredom, but this wasn't even the case at Fiore. The waiter gave us our space, but came back exactly when needed.
We both shared our meals, so we got to enjoy two dishes each. Both we delicious in their own way. The marinara sauce we had wasn't too overpowering and the pizza was crispy, but still soft and warm. It's a pretty good amount of food and we were pleased when we left.
Next time I'm on 17th and in the mood for a nice lunch or dinner, I'm going to stop saying I should go in and just do it! I like Fiore Cantina just fine!
