Istanbul - Post Report Question and Answers
What do people who suffer from environmental or food allergies need to know?
Due to how great the grocery shopping is, it was easy to navigate food issues for our family when cooking. Eating out was more challenging, but solely because of the language issue. If I ate out with a Turkish speaker, Turkish restaurants were very willing to navigate food allergies. Gluten-free products are readily available in all grocery stores. - Aug 2021
For food allergies, you'll need to learn some Turkish to communicate your requirements to waitstaff. - Sep 2017
