Delicious gluten free pasta! The manager and waitstaff seem knowledgeable and right away said they were putting on a separate pot of water to boil for the gf pasta.
The staff was knowledgeable about gluten. The waitress didn't try to offer us bread when we said we were gf, which is always a good sign. The food is really good, too. We had the Pollo con Zucchini, and it was amazing. The caprese appetizer was also fresh and delicious.
Options are pretty limited for GF in the O'Hare airport. This place at least has GF options clearly marked on their menu and there are several to choose from. I've been here twice and gotten the Caprese Salad and the Chicken with Zucchini. The description on the Chicken said "bruschetta" so I double checked that there was no bread. It's just the tomato topping part actually and the waitress seemed informed about GF. I am generally very sensitive, but maybe a little less so now, and I did not get sick.
After the one hour security line I was hungry, and we all know our options in airports are nearly non existent. I was not looking forward to my normal solution of a hard boiled egg and cheese stick from the Hudson News. Then I stumbled upon the Tuscany Cafe down towards the end of terminal B (by B16-B18). They have a gluten free menu and the server understood my concerns. The Pollo con Zucchini was very good and the service was quick so I was able to catch my flight. Great atmosphere too if you want to escape the airport rush for a moment. Safe travels.
