Thanks to Tabitha for this information on Cheesecake Factory:
I have found that the Cheesecake Factory is EXTREMELY allergy friendly, and there were actually many options. I have eaten there 3 times recently (and at different locations) and I haven’t been “soyed” once. They will also let you know if there is soybean oil in the food.
We don’t have any close to us, but we’ll definitely look for one next time we’re on the road.
