Not a bad place, but I would go for a seat inside the restaurant.
I visited Il Fornaio with a group of seven who were in from out of town. For some reason they really wanted to sit on the "patio" which is really just the area outside of the main restaurant right next to the slot machines. As you can imagine that made for a really loud meal and the main thing that kept me from rating Il Fornaio any higher.
We were here on a Sunday night, and had to wait about 10-15 minutes to be seated. Like any Italian place, you get plenty of bread with vinegar and oil to tide you over while you decide on what to have. I went for the margherita pizza, which was more than I could handle. If I recall correctly it was in the 10-15 dollar range. Most of the other entrees are a bit more pricey. The wait staff was friendly but a little too attentive for my taste. I don't need to be asked every 4 minutes if I'm ok, or have someone reach through my conversation to refill my water that's not even half gone.
If I go back here, I'll definitely get inside seating. The food is slightly above the Olive Garden. I wouldn't absolutely rule this place out for a second visit, but it's far from your best option.
