Can you google the restaurant? Sometimes they'll have nutritional facts listed with their food items....

I've gone to restaurants and ordered successfully off the "gluten free" menu that many seem to have these days.

I've also gone out to eat, and decided I wouldn't after reading the menu and just enjoyed the company and a glass of unsweetened ice tea... Imma bit paranoid about what I eat since I started this incredible WOE...

Wishing you all the best on your journey!
