Majority of people suffering from celiac disease or gluten intolerance prefer gluten-free food most of the times. Having several health benefits like good digestion is also one of the reasons that many people have switched to a gluten free diet.
A gluten-free restaurant will frequently be a partner of the (GFRAP) program. It means they must follow the tight rules for supplying free food, and provide a big menu of GF food. In these cases, you expect that most people who dish food within the eatery, as well as the owners', are totally aware of all of the needs of a celiac.
Often what most celiac and gluten intolerant people are trying to miss out on in their dining experience is the hassle involved when asking for g-free foods or describing what the disease is
Of equal importance is making sure whether you have asked or not, that you are not mistakenly 'poisoned' by hidden gluten ingredients or by cross contamination.
On the subject of asking about g free, it unquestionably helps if the gluten-free restaurant openly exhibits signs expressing that they are gluten free knowledgeable or have g-free menu foods.
If they do not, some celiac likes to display a gluten-free definition card which aptly describes the disease and what foods they can not consume. Preferably a celiac should have dining companions who are supportive, maybe even ones who will proactively request the gluten-free query for them.
