HI
I am a ceoliac and I find eating in Calis so much easier than eating here.
I downloaded the allergy cards on to my phone so that the Turkish translation of my condition was to hand and I showed it when required.
Staff would tell me what I could eat off the menu and several places asked what it was that I wanted and would alter it so I could eat there.
I found Casa Di Mama. Harems and most of all Barbella's to be exceptionally helpful.
Barbella's even asked me for a recipe for a desert i could eat and created a gluten free brownie, which I hear is still on the menu. I am so excited to see that they make gluten free bread now (yum)
I think you will find them all very helpful and I hope that you have a lovely holiday
